[v5 00/14] 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
AST2600, AST2500 and AST2400 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.

Changes in v5:
  - Separate main ASPEED SPI driver patch into different parts.
    * basic support.
    * decoded range adjustment.
    * clock settings.
  - Add support customized decoded range.
  - Add AST2400 platform support.
