arm: mmu: Add missing volatile for reading SCTLR register
Add 'volatile' qualifier to the asm statement in get_cr()
so that the statement is not optimized out by the compiler.
(http://comments.gmane.org/gmane.linux.linaro.toolchain/5163)
Without the 'volatile', get_cr() returns a wrong value which
prevents enabling the MMU and later causes a PCIE VA access
failure.
