[U-Boot] [PATCH] mtd/spi: Add MT35XU512ABA1G12 NOR flash support

[Yogesh Gaur]

Add MT35XU512ABA1G12 parameters to NOR flash parameters array. Since the
manufactory ID is changed to 0x2C, add it for micron and using it for
relevant settings.

The MT35XU512ABA1G12 only supports 1 bit mode and 8 bits. It can't support
dual and quad. Supports subsector erase with 4KB granularity, have support
of FSR(flag status register) and flash size is 64MB.
