drm/bridge: anx7625: change the gpiod_set_value API

Use gpiod_set_value_cansleep() instead of gpiod_set_value()
to fix the below call trace in the boot log:

[    5.690534] Call trace:
[    5.690536]  gpiod_set_value+0x40/0xa4
[    5.690540]  anx7625_runtime_pm_resume+0xa0/0x324 [anx7625]
[    5.690545]  __rpm_callback+0x48/0x1d8
[    5.690549]  rpm_callback+0x6c/0x78

Certain GPIO controllers require access via message-based buses
such as I2C or SPI, which may cause the GPIOs to enter a sleep
state. Therefore, use the gpiod_set_value_cansleep().
