b6fe8bc67d mtd: hyperbus: move direct mapping setup to AM654 HBMC driver 
The Hyperbus core expects that HyperFlash is always directly mapped for
both read and write, but in reality this may not always be the case, e.g.
Renesas RPC-IF has read only direct mapping. Move the code setting up the
direct mapping from the Hyperbus core to thh TI AM554 HBMC driver.

b07079f164 mtd: hyperbus: Add driver for TI's HyperBus memory controller 
Add driver for HyperBus memory controller on TI's AM654 SoC. Programming
IP is pretty simple and provides direct memory mapped access to
connected Flash devices.

Add basic support for the IP without DMA. Second chip-select is not
supported for now.
