Sherman Yin 7418b5cc81 pinctrl: Rename Broadcom Capri pinctrl driver 
To be consistent with other Broadcom drivers, the Broadcom Capri pinctrl
driver and its related CONFIG option are renamed to bcm281xx.

Devicetree compatible string and binding documentation use
"brcm,bcm11351-pinctrl" to match the machine binding here:
Documentation/devicetree/bindings/arm/bcm/bcm11351.txt

This driver supports pinctrl on BCM11130, BCM11140, BCM11351, BCM28145
and BCM28155 SoCs.
