The probe function checks usbmisc to be NULL in the beginning. Without
this patch the can only be loaded once.

This driver will be used for every Freescale SoC which has this misc
memory layout to control the basic usb handling. So better name this
driver, function and struct names in a more generic way.

Staticize usbmisc_imx6q_drv_init/exit() to fix the following sparse warnings:

drivers/usb/chipidea/usbmisc_imx6q.c:147:12: warning: symbol 'usbmisc_imx6q_drv_init' was not declared. Should it be static?
drivers/usb/chipidea/usbmisc_imx6q.c:153:13: warning: symbol 'usbmisc_imx6q_drv_exit' was not declared. Should it be static?

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

CONFIG_HOTPLUG is going away as an option so __devexit is no

i.MX usb controllers share non-core registers, which may include
SoC specific controls. We turn it into a usbmisc device and usbmisc
driver set operations needed by ci13xxx_imx driver.

For example, Sabrelite board has bad over-current design, we can
usbmisc to disable over-current detection.
