mm: memblock: do not enforce current limit for memblock_phys* family
Until commit 92d12f9544b7 ("memblock: refactor internal allocation
functions") the maximal address for memblock allocations was forced to
memblock.current_limit only for the allocation functions returning
virtual address. The changes introduced by that commit moved the limit
enforcement into the allocation core and as a result the allocation
functions returning physical address also started to limit allocations
to memblock.current_limit.
This caused breakage of etnaviv GPU driver:
etnaviv etnaviv: bound 130000.gpu (ops gpu_ops)
etnaviv etnaviv: bound 134000.gpu (ops gpu_ops)
etnaviv etnaviv: bound 2204000.gpu (ops gpu_ops)
etnaviv-gpu 130000.gpu: model: GC2000, revision: 5108
etnaviv-gpu 130000.gpu: command buffer outside valid memory window
etnaviv-gpu 134000.gpu: model: GC320, revision: 5007
etnaviv-gpu 134000.gpu: command buffer outside valid memory window
etnaviv-gpu 2204000.gpu: model: GC355, revision: 1215
etnaviv-gpu 2204000.gpu: Ignoring GPU with VG and FE2.0
Restore the behaviour of memblock_phys* family so that these functions
will not enforce memblock.current_limit.
