Fixed coverity and compiler warning in drivers/spi/u8500_spi.c.
Also removed a variable which is no longer needed after the
GPIO-handling was removed from the driver.

Copied the GPIO configurator written for the Linux kernel.
The Nomadik db8500 GPIO driver. Purpose is to be able
to just cut-n-paste the GPIO config from Linux to U-boot.
Also at the same time remove the obsolete and old
gpio_alt_funcenable/disable methods.
Now all is configured using a table in u8500.c.
Now drivers doesn't have to worry about setting up the GPIO pins.
Actually no driver today uses GPIO pins directly, only via
hardware blocks within db8500. Functions are still added
to be able to interact directly with a GPIO pin. This also
cleaned up a lot of driver by not having to bit manipulate GPIO
registers them self.
The new driver is called db8500_gpio and placed in driver/gpio/.
Functions are in include/db8500_gpio.h:
void db8500_gpio_set_pull(unsigned gpio, enum db8500_gpio_pull pull);
void db8500_gpio_make_input(unsigned gpio);
int db8500_gpio_get_input(unsigned gpio);
void db8500_gpio_make_output(unsigned gpio, int val);
void db8500_gpio_set_output(unsigned gpio, int val);
And for the configurator in include/db8500_pincfg.h:
void db8500_gpio_config_pins(pin_cfg_t *cfgs, size_t num);
All in all the final binary size has decreased.
This is only done for db8500 nomadik GPIO. The code for gpio
expanders has not been touched.
All references to Nomadik has been removed in this driver.
Only db8500 is left.

Moved clock code from board/st/u8500/u8500.c to
cpu/arm_cortexa9/db8500/clock.c.
Remove code to simulate Maja clocks.
