ARM: 8681/1: make VMSPLIT_3G_OPT depends on !ARM_LPAE
When both enable CONFIG_ARM_LPAE=y and CONFIG_VMSPLIT_3G_OPT=y, which
means use PAGE_OFFSET=0xB0000000 with ARM_LPAE, the kernel will boot
fail and stop after uncompressed:
Starting kernel ...
Uart base = 0x20001000
watchdog reg = 0x20013000
dtb addr = 0x80840308
Uncompressing Linux... done, booting the kernel.
For ARM_LPAE only support 3:1, 2:2, 1:3 split of TTBR1, which mention in:
http://elinux.org/images/6/6a/Elce11_marinas.pdf - p16
So we should make VMSPLIT_3G_OPT depends on !ARM_LPAE to avoid trigger
this bug.
