ARM/i.MX53: fix compiler warning
The code wants to test if the lower 16bits of the content of
MX53_CSD0_BASE_ADDR and SDRAM_COMPARE_CONST1 are identical. The assembly
this code was derived from did:
mov r5, r0, lsl #16
mov r6, r7, lsl #16
cmp r5, r6
In C this is better written with masks which is better readable and
avoid this compiler warning:
arch/arm/mach-imx/esdctl-v4.c:613:63: warning: result of '305419896 << 16' requires 46 bits to represent, but 'int' only has 32 bits [-Wshift-overflow=]
