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.
