[PATCH v2] pinctrl: single: set function name when adding function

[Drew Fustini <drew@beagleboard.org>]

pcs_add_function() fails to set the function name in struct pcs_function
when adding a new function.  As a result this line in pcs_set_mux():

        dev_dbg(pcs->dev, "enabling %s function%i\n",
                func->name, fselector);

prints "(null)" for the function:

pinctrl-single 44e10800.pinmux: enabling (null) function0
pinctrl-single 44e10800.pinmux: enabling (null) function1
pinctrl-single 44e10800.pinmux: enabling (null) function2
pinctrl-single 44e10800.pinmux: enabling (null) function3

With this fix, the output is now:

pinctrl-single 44e10800.pinmux: enabling pinmux-uart0-pins function0
pinctrl-single 44e10800.pinmux: enabling pinmux-mmc0-pins function1
pinctrl-single 44e10800.pinmux: enabling pinmux-i2c0-pins function2
pinctrl-single 44e10800.pinmux: enabling pinmux-mmc0-pins function3
