[PATCH] powerpc/83xx/mpc8349emitx: Drop unused variable

[Uwe Kleine-König]

Commit 5d354dc35ebb ("powerpc/83xx/mpc8349emitx: Make
mcu_gpiochip_remove() return void") removed the usage of the variable
ret, but failed to remove the variable itself, resulting in:

	arch/powerpc/platforms/83xx/mcu_mpc8349emitx.c: In function ‘mcu_remove’:
	arch/powerpc/platforms/83xx/mcu_mpc8349emitx.c:189:6: error: unused variable ‘ret’ [-Werror=unused-variable]
	  189 |  int ret;
	      |      ^~~

So remove the variable now.
