Instead of depends on GPIOLIB and having to run around in
Kconfig menus looking for why your device is not available,
simply select it from the pin control drivers that need it.

The Kconfig for GPIOLIB is improved, selectable and this
should "just work".

configured. Update is_enabled flag in config_set() so that it can
reflect GPIO status correctly. Also modify EN_CTL register based on

Merge tag 'sh-pfc-for-v4.15-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers into devel

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.
