mfd: vexpress-sysreg: Check the return value of devm_gpiochip_add_data()

Browse source

commit 1efbee6852 upstream.

Commit 974cc7b934 ("mfd: vexpress: Define the device as MFD cells")
removed the return value check from the call to gpiochip_add_data() (or
rather gpiochip_add() back then and later converted to devres) with no
explanation. This function however can still fail, so check the return
value and bail-out if it does.
