PATCH 1/1 mtd: spi-nor: Add support for Micron n25q032a

The N25Q032A is identical to the N25Q032 except it has a different supply voltage range. Therefore, it has a new JEDEC ID.

I know the original entry doesn't specify this, but does this flash support 4K sectors and dual read? We should add the flags.

Yes it does support 4k erase subsectors and, quad and dual fast read.

We can create a new patch to update the flags.
