Add support for w25q512jvq. This is of the same series chip with
w25q256jv, which is already supported, but with size doubled and
different JEDEC ID.
Tested on Intel whitley platform with dd from/to the flash for
read/write respectly, and flash_erase for erasing the flash.

Sysbot has reported a warning where a kmalloc() attempt exceeds the

this corruption and others.

When modifying pmd through THP, invalid address access may occurs in the tlb
handler. Because the tlb handler loads value of pmd twice, one is used for huge
page testing and the other is used to load pte. So these two values may be
different:
