[v4 00/12] Add ASPEED SPI controller driver

[Chin-Ting Kuo]

This patch series aims to porting ASPEED FMC/SPI memory controller
driver with spi-mem interface. spi-mem dirmap framework is also
synchronized from Linux. These patches have been verified on both
AST2600 and AST2500 EVBs.

Changes in v2:
  - Separate defconfig files from the SPI driver patch.
  - Use "if (CONFIG_IS_ENABLED(SPI_DIRMAP))" to wrap
    spi_dirmap related functions.
  - Add Winbond w25q512jv flash ID.

Changes in v3:
  - Get AHB bus clock frequency from the function parameter.
  - Fix a grammatical error in spi-mem.h.

Changes in v4:
  - Fix bug when SPI_NOR_4B_OPCODES flag is set.
