Zbigniew Bodek 1e17cf74b6 Delete obsolete and unused PJ4B CPU functions 
Since PJ4Bv7 uses armv7_ CPU functions only pj4b_config
function is necessary. Remove obsolete routines.

* Cache operations:
*
* We define the following primitives:
*
* icache_sync_all Synchronize I-cache
* icache_sync_range Synchronize I-cache range
*
* dcache_wbinv_all Write-back and Invalidate D-cache
* dcache_wbinv_range Write-back and Invalidate D-cache range
* dcache_inv_range Invalidate D-cache range
* dcache_wb_range Write-back D-cache range
*
* idcache_wbinv_all Write-back and Invalidate D-cache,
* Invalidate I-cache
* idcache_wbinv_range Write-back and Invalidate D-cache,
* Invalidate I-cache range
*
* Note that the ARM term for "write-back" is "clean". We use
* the term "write-back" since it's a more common way to describe
* the operation.
*
* There are some rules that must be followed:
*
* ID-cache Invalidate All:
* Unlike other functions, this one must never write back.
* It is used to intialize the MMU when it is in an unknown
* state (such as when it may have lines tagged as valid
* that belong to a previous set of mappings).
*
* I-cache Synch (all or range):
* The goal is to synchronize the instruction stream,
* so you may beed to write-back dirty D-cache blocks
* first. If a range is requested, and you can't
* synchronize just a range, you have to hit the whole
* thing.
*
* D-cache Write-Back and Invalidate range:
* If you can't WB-Inv a range, you must WB-Inv the
* entire D-cache.
*
* D-cache Invalidate:
* If you can't Inv the D-cache, you must Write-Back
* and Invalidate. Code that uses this operation
* MUST NOT assume that the D-cache will not be written
* back to memory.
*
* D-cache Write-Back:
* If you can't Write-back without doing an Inv,
* that's fine. Then treat this as a WB-Inv.
* Skipping the invalidate is merely an optimization.
*
* All operations:
* Valid virtual addresses must be passed to each
* cache operation.
