Magnus Damm 2eeec85638 sh: intc - convert board specific r2d code
This patch converts the board specific interrupt code for r2d to make
use of intc. While at it we improve the Kconfig to avoid confusion.

- Two sets of interrupt tables exist - one for R2D-1 and one for R2D-PLUS.
- R2D-1 and R2D-PLUS use the same irq constants.
- R2D-1 has AX88796 support, R2D-PLUS does not hook up that IRQ.
- R2D-PLUS has KEY support, R2D-1 does not hook up that IRQ.
- The number and order of IRQ values are disconnected from register bits.
- Interrupt sources now start from IRQ 100.
- The machvec demux function converts from irlm IRQ 0-14 to IRQ 100++.

Tested on R2D-1 and R2D-PLUS boards.

Version 2 adds CONFIG_RTS7751R2D_1 and CONFIG_RTS7751R2D_PLUS together
with intc structured as __initdata.

Magnus Damm 5ca95c48f1 sh: fix cf support on r2d boards
This patch makes sure cf support is enabled on R2D-PLUS but disabled
on R2D-1. Without this fix R2D-1 boards hang on bootup.

Paul Mundt 9c57548f17 sh: rts7751r2d board updates.
This tidies up some of the rts7751r2d mess and gets it booting
again. Update the defconfig, too.

Some of these were dropped in the header directory rework, add
the few missing ones back in.
