davinci: da850-evm: UI expander gpio_set_value can sleep, use _cansleep
When the RMII PHY on the UI board is enabled with CONFIG_DA850_UI_RMII
then then following will be printed to the console when warnings are
also enabled:
WARNING: at drivers/gpio/gpiolib.c:1567 __gpio_set_value+0x4c/0x5c()

<snip>
Traced the WARN_ON to the gpio_set_value(rmii_sel,0) call in
da850_evm_setup_emac_rmii. Replacing the call with the _cansleep variant
results in no more warning. Also replacing the gpio_set_value calls in the
teardown function.
