drivers/spi: Add support for Micron N25Q128A
Although we have already support for the flash chip N25Q128 there is a
similar type available which has the same geometry and opcodes but
unfortunately a slightly different device type ID. While the already
supported N25Q128 has the ID 0xbb18 this one has the ID 0xba18.
To make both types available in the flash support table, use N25Q128A as
the flash name. This name can be found in the datasheet which can be
found here:
https://www.micron.com/~/media/documents/products/data-sheet/nor-flash/serial-nor/n25q/n25q_128mb_3v_65nm.pdf
TEST=Booted and verified that MRC cache could be written
