In Cygnus SOC touch screen controller registers are shared with ADC and
flex timer. Using readl/writel could lead to race condition. So touch
screen driver is enhanced to support register access using syscon framework
API's to take care of mutually exclusive access.

The third compatible string "brcm,brcmnand" in bcm-cygnus.dtsi nand node
is incorrect, redundant and should be removed. "brcm,brcmnand" is meant to
be used by STB based Broadcom SoCs. All iProc based SoCs should use
"brcm,nand-iproc".

This patch enables touchscreen support on bcm958300k and bcm958305k.
Touchscreen is connected to these boards through the bcm9hmidc daughter
card, and therefore also adding bcm9hmidc.dtsi that describes the
daughter card
