* add a real AT91 GPIO driver instead of header inline code
* resolve the mixing of port and pins
* change board config files to use new driver
* add macros to gpio to realize backward compatibility

This is a minimal driver, so far only managing output. It will
be used by the mxc_spi.c driver.

Initial support for NXP's 4 and 8 bit I2C gpio expanders
(eg pca9537, pca9557, etc). The CONFIG_PCA953X define
enables support for the devices while the CONFIG_CMD_PCA953X
define enables the pca953x command. The CONFIG_CMD_PCA953X_INFO
define enables an 'info' sub-command which provides summary
information for the given pca953x device.
