MLK-12527-1 mxc_keyb: Add MXC keyboard driver

The i.MX6SL EVK needs this driver in android fastboot support. Add
this driver to u-boot.

To use the driver, user must define:

CONFIG_MXC_KPD          Enable the driver
CONFIG_MXC_KEYMAPPING   Key mapping matrix
CONFIG_MXC_KPD_COLMAX   The column size of key mapping matrix
CONFIG_MXC_KPD_ROWMAX   The row size of the key mapping matrix
