This patchset introduces DT bindings and driver for the Amlogic Meson A1
SPI flash controller (A113L SoC).

The existing spi-meson-spifc driver is incompatible with the A1 SPIFC
at all.

The implementation has been tested on the Amlogic A113L SoC based device
connected with ESMT F50L1G41LB spinand flash.

This patchset has dependencies on the A1 clock series which is still
under review [1].

Changelog:
  v2 since v1 at [2]:
    - Make cosmetic changes
