Subject: [PATCH] arm64: mvebu: Modify the A8K SPI and I2C config in DTS

Align the Armada-8040-db and Armada-7040-db SPI and I2C
DTS settings with latest DB settings:
- 8040-db: disable i2c0 and spi0 on AP (MPPs are reserved for SDIO)
- 8040-db: disable cps_i2c0 on CP1
- 8040-db: enable spi1 on CP1 (the new location of the boot flash)
  The spi1 on CP1 is aliased as spi0 since this is the way
  the driver enumerates it.
