spi: clps711x: Provide label argument for devm_gpio_request

Browse Source 
The label argument was removed by commit 989847967c
spi: clps711x: Use devm_gpio_request(), add it back.
This makes it easier to know the gpio usage in /sys/kernel/debug/gpio.

Also remove unnecessary gpio_is_valid() checking, devm_gpio_request() returns
error if the requested gpio is invalid.
