pinctrl: sh-pfc: Make pinmux_cfg_reg.var_field_width[] variable-length
pinmux_cfg_reg.var_field_width[] is actually a variable-length array, terminated by a zero, and counting at most r_width entries. Usually the number of entries is much smaller than r_width, so the ability to catch bugs at compile time through an "excess elements in array initializer" warning is fairly limited. Hence make the array variable-length, decreasing kernel size slightly. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Simon Horman <horms+renesas@verge.net.au>
