Input: matrix_keypad - use request_any_context_irq()
When trying to use the matrix-keypad driver with GPIO drivers that
require nested irq handlers (e.g. I2C GPIO adapters like PCA9554),
request_irq() fails because the GPIO driver requires a threaded
interrupt handler.
Use request_any_context_irq() to be able to use any GPIO driver as
keypad driver.
