gpio: pca953x: enfore type for i2c_smbus_write_word_data()

Browse source

The commit 9b8e3ec343 ("gpio: pca953x: Use correct u16 value for register
word write") fixed regression in pca953x_write_regs(). At the same time the
solution introduced a sparse warning:

drivers/gpio/gpio-pca953x.c:168:39: warning: incorrect type in argument 3 (different base types)
drivers/gpio/gpio-pca953x.c:168:39:    expected unsigned short [unsigned] [usertype] value
drivers/gpio/gpio-pca953x.c:168:39:    got restricted __le16 [usertype] <noident>

Fix the code by enforcing the type of i2c_smbus_write_word_data() parameter.
