Add eMMC pinmux and mmc2 related bits. We keep the mmc2
controller disabled as it conflits with gpmc/NAND.
To enable emmc, simply set mmc2 controller node to "okay"
and set the gpmc node to "disabled" and change the
SelEMMCorNAND gpio-hog to output-high.

ldo1_reg in addition to being connected to the io lines is also
connected to the card detect line. On card removal, omap_hsmmc
driver does a regulator_disable causing card detect line to be
pulled down. This raises a card insertion interrupt and once the
MMC core detects there is no card inserted, it does a
regulator disable which again raises a card insertion interrupt.
This happens in a loop causing infinite MMC interrupts.
Fix it by making ldo1_reg as always_on.

If a GPIO driver uses gpiochip_add_pin_range() (which is usually the
case for GPIO/PFC combos), the GPIO hogging mechanism configured from DT
doesn't work:
requesting hog GPIO led1-high (chip sh73a0_pfc, offset 20) failed
The actual error code is -517 == -EPROBE_DEFER.
The problem is that PFC+GPIO registration is handled in multiple steps:
1. pinctrl_register(),
2. gpiochip_add(),
3. gpiochip_add_pin_range().
Configuration of the hogs is handled in gpiochip_add():
gpiochip_add
of_gpiochip_add
of_gpiochip_scan_hogs
gpiod_hog
gpiochip_request_own_desc
__gpiod_request
chip->request
pinctrl_request_gpio
pinctrl_get_device_gpio_range
However, at this point the GPIO controller hasn't been added to
pinctrldev_list yet, so the range can't be found, and the operation fails
with -EPROBE_DEFER.
To fix this, add a "gpio-ranges" property to the gpio device node, so
the ranges are added by of_gpiochip_add_pin_range(), which is called by
of_gpiochip_add() before the call to of_gpiochip_scan_hogs().
