Andy Shevchenko 9ed2bfb3e3 staging: fbtft: convert fbtft_reset() to be non-atomic 
First of all, fbtft in current state doesn't allow to override GPIOs to be
optional, like "reset" one. It might be a bug somewhere, but rather out of
scope of this fix.

Second, not all GPIOs available on the board would be SoC based, some of them
might sit on I2C GPIO expanders, for example, on Intel Edison/Arduino, and thus
any communication with them might sleep.

Besides that using udelay() and mdelay() is kinda resource wasteful.

Summarize all of the above, convert fbtft_reset() function to non-atomic
variant by using gpio_set_value_cansleep(), usleep_range(), and msleep().
