[U-Boot] [PATCH 1/5] video: mb862xx: support Coral-PA controller

[Anatolij Gustschin <agust@denx.de>]

Add detection of Coral-PA and configure Coral CCF an MMR parameters
using CONFIG_SYS_MB862xx_CCF and CONFIG_SYS_MB862xx_MMR macros.
Use CCF and MMR parameters for Coral-P Eval. Board if the appropriate
macros weren't defined.
