Davinci: cpintc host map configuration

Browse source

Host map configuration instructs the interrupt controller to route interrupt
channels to FIQ or IRQ lines.  Currently, DA8xx family of devices leave these
registers at their reset-default values.

TNETV107X however does not have sane reset defaults, and therefore this
architecture needs to reconfigure the host-map such that channels 0 and 1
go to FIQ, and the remaining channels raise IRQs.

This patch adds an optional host map argument to cp_intc_init() for this.
