[RESEND PATCH 0/2] Enable SPI on A64/Pine64

[Stefan BrÃns]

The A64 SPI controller is compatible to the H3/H5 controller, i.e. same
registers and same queue depth.

The Pine64 exposes both controllers on the PI-2 and Euler connectors.

Tested/verified with logic analyser and spidev_test using MOSI/MISO loopback.

Note: spi0 on the A64 may conflict with the eMMC controller, as the MISO pin is
also used for the HS400 eMMC data strobe. This is only a concern if the board
uses eMMC (does not apply to the Pine64) *and* is using HS400 mode. The same
pin conflict exists for the H5.
