sysutils/cpu-microcode*: support early loading of AMD ucode

Browse Source 
Install the AMD ucode in /boot/firmware for early loading just like
is done for intel.  Update the instructions for early loading to
reflect that AMD is now supported too.

This port includes an RC script, which is one of two methods to update
the CPU microcode on a FreeBSD system.
1. The first method does not require the RC script included here and is
only supported with Intel processors. It is the preferred method,
because it ensures that any CPU features introduced by a microcode
update are visible to the kernel by applying the update before the
kernel performs CPU feature detection.
1. Early loading.
This method does not use the RC script included here.
This is the preferred method, because it ensures that any CPU features
added or removed by a microcode update are visible to the kernel by
applying the update before the kernel performs CPU feature detection.
To enable updates using the first method, add the following lines to
To enable updates using early loading, add the following lines to
/boot/loader.conf:
cpu_microcode_load="YES"
and the appropriate one of these lines:
cpu_microcode_name="/boot/firmware/intel-ucode.bin"
cpu_microcode_name="/boot/firmware/amd-ucode.bin"
The microcode update will be loaded when the system is rebooted.
2. The second method, which uses the RC script included here, can be
enabled by adding the following line to /etc/rc.conf:
