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.

There is nothing special to be done for interrupts
which can wakeup the device from sleep on CP-INTC,
but not having a set_wake implemented prevents use
of common drivers which expect this function to be
implemented for all wakeup interrupt sources.
This patch fixes the issue encountered when using the
omap-rtc driver on DA850. On DA850 the RTC alarm
interrupt is used to wake up the SoC from deep sleep
mode. Without this patch, the disable_irq_wake throws
an unbalanced wake disable warning while resuming
because the previous enable call fails for lack of
set_wake implementation.

There have accumulated quite a lot of them after the code reorganizations...
In several cases I had to replace #include <linux/dma-mapping.h> which wasn't
needed directly but happened to #include <linux/err.h> which was needed.
