This patch adds the necessary methods resolution to the sdhci_xenon
driver which are required to configure UHS modes for SD/MMC devices.
Apart from the two generic routines, the custom sdhci_xenon_set_uhs_timing
function is responsible for setting the SDHCI_HOST_CONTROL2 register
with appropriate mode select values - in case of HS200 and HS400
they are non-standard.

Until now the "no-1-8-v" DT flag wrongly disabled the SDHCI_CAN_VDD_180
- slot 1.8V power supply capability, whereas it refers to the signaling
voltage. Fix the sdhci_xenon_read_4 and allow to disable the UHS modes
depending on the DT property or PHY slow mode. While at it - make sure
the unsupported 1.2V signaling is always disabled and not reported
in the bootverbose log.

With this change the host controller drivers can set the MMC capabilities
(e.g. using mmc_fdt_parse() helper) before calling sdhci_init_slot().
This way the configuration dump (eg. in bootverbose) can include the

NAT table mappings list only the source and destination IP, the source
and destinaion port numbers, and their mappings. But the protocol is not
listed. Now that Facebook and Google use QUIC, seeing port 443 in in a
list of active NAT sessions could mean 443/tcp or 443/udp. This patch
adds the protocol to the listing to aid in determining whether HTTPS is
TCP or QUIC in a NAT mapping listing. This also helps differentiatinete
between other protocols such as ICMP, ESP, and AH in ipnat list of active
sessions.

DBG2 ACPI table description [1] specifies three subtypes
related to 16550 UART:
0x0 - 16550 compatible
0x1 - 16550 subset
0x12 - 16550 compatible with parameters defined in Generic Address Structure (GAS)
It turned out however, that the Windows OS treats 0x0 subtype as
legacy x86 UART with 8-bit access. ARM SoCs can use types 0x1 (16550 with
fixed mmio32 access) or 0x12 (16550 with fully respected GAS contents).
Switch Marvell SoCs ACPI UART subtype to 0x1 - thanks to that the same firmware
can run properly with UART output in FreeBSD, Windows 10, Linux and ESXI
hypervisor. Tests showed the older firmware versions that use 0x0
UART subtype in SPCR table continue to display output properly.

HS200 and HS400 speeds can be enabled either with 1.2, or 1.8V signaling voltage.
Because of that we have four cabability flags: MMC_CAP_MMC_HS200_120,
MMC_CAP_MMC_HS200_180, MMC_CAP_MMC_HS400_120, MMC_CAP_MMC_HS400_180.
MMC logic only enables HS200/HS400 mode if both flags are set for the corresponding speed.
Fix that by being more permissive in host timing cap check.

The geom_gate API provides 2 distinct paths for exchanging error
details between the kernel and the userland client: Including an error
code in the g_gate_ctl_io structure passed in the ioctl(2) call or
having the ioctl(2) call return -1 with an error code in errno. The
latter reflects errors in the ioctl(2) call itself whilst the former
reflects errors within the geom_gate instance.
The G_GATE_CMD_START ioctl blocks waiting for an I/O request to be
directed to the geom_gate instance and the wait can fail
(necessitating an error return) if the geom_gate instance is destroyed
or if the msleep(9) fails. The code previously treated both error
cases indentically: Returning ECANCELED as a geom_gate instance error
(which the ggatec treats as a fatal error). Whilst this is the correct
behaviour if the geom_gate instance is destroyed, a msleep(9) failure
is unrelated to the geom_gate instance itself and should be reported
as an ioctl(2) "failure". The distinction is important because
msleep(9) can return ERESTART, which means the system call should be
retried (and this will occur automatically as part of the generic
syscall return processing).
This change alters the msleep(9) handling to directly return the error
code from msleep(9), which ensures ERESTART is correctly handled,
rather than being treated as a fatal error.
