GPIO is expected to be disabled iff PIN_CONFIG_BIAS_HIGH_IMPEDANCE is
configured. Update is_enabled flag in config_set() so that it can
reflect GPIO status correctly. Also modify EN_CTL register based on

pinctrl: sh-pfc: Updates for v4.15

  - Add SDHI and DRIF pin groups on R-Car H3 ES2.0,
  - Add USB3.0 host pin groups on R-Car H3 (ES1.x and ES2.0),
  - Add EthernetAVB and USB2.0 host pin groups on R-Car D3.

If the gmac-m1 optimization(bit10) is selected, the gpio function
of gmac pins is not valid. We may use the rmii mode for gmac interface,
the pins such as rx_d2, rx_d3, which the rgmii mode used, but rmii not
used could be taken as gpio function. So gmac_rxd0m1 selects the bit2,
and gmac_rxd0m3 select bit10 is more correct.

This restores the ability to build firmware directly into the kernel by
pruning the original Makefile to the necessary minimum.  The default for
EXTRA_FIRMWARE_DIR is now the standard directory /lib/firmware/.
