[PATCH] pinctrl: oxnas: remove set but not used variable 'arg'

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/pinctrl/pinctrl-oxnas.c: In function oxnas_ox810se_pinconf_set:
drivers/pinctrl/pinctrl-oxnas.c:905:6: warning: variable arg set but not used 
[-Wunused-but-set-variable]
drivers/pinctrl/pinctrl-oxnas.c: In function oxnas_ox820_pinconf_set:
drivers/pinctrl/pinctrl-oxnas.c:944:6: warning: variable arg set but not used 
[-Wunused-but-set-variable]

It is never used since commit 4b0c0c25fa79 ("pinctrl:
oxnas: Add support for OX820"), so can be removed.
