[PATCH] ARM: mmu: Fix MT_MEMORY and MT_MEMORY_NONCACHED pte flags

[Santosh Shilimkar]

The commit f1a2481c0 sets up the default flags for MT_MEMORY and
MT_MEMORY_NONCACHED memory types. L_PTE_USER flag is wrongly
set as default for these entries so remove it. Also adding
the 'L_PTE_WRITE' flag so that these pages become read-write
instead of just being read-only
