Currently, the Renesas pin control driver supports pins that can switch
their I/O voltage levels between either 1.8V and 3.3V, or between 2.5V
and 3.3V. However, some SoCs have pins that can switch between 1.8V and
2.5V.
Add support for this by replacing the separate SH_PFC_PIN_CFG_IO_VOLTAGE
capability and voltage level flags by a 2-bit field, to cover three
possible I/O voltage switching options.

AVB[01]_{MAGIC,MDC,MDIO,TXCREFCLK} are registered as both
PINMUX_SINGLE(fn) and PINMUX_IPSR_GPSR(fn) in the pinmux_data array.
The latter are correct, hence remove the former.
Without this fix, the Ethernet PHY is not operational on the MDIO bus.

The V3U SoC has several unlock registers, one per register group. They
reside at offset zero in each 0x200 bytes-sized block.
To avoid adding yet another table to the PFC implementation, this

address in sh_pfc_soc_info::unlock_reg.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

By default on startup all the pin types are configured to
PINMUX_TYPE_NONE (in sh_pfc_map_pins()), when pin is set as GPIO the
pin type is updated to PINMUX_TYPE_GPIO. But the type is not updated
when the pin is set as a function in sh_pfc_pinctrl_pin_set() or
sh_pfc_pinctrl_group_set() calls (these calls only set the MUX if
the pin type is PINMUX_TYPE_NONE ie unused).
So with the current implementation pin functionality could be overwritten
silently, for example if the same pin is added for SPI and serial.
This patch makes sure of updating pin type after every successful call to
sh_pfc_config_mux() and thus fixing from pin functionality to be
overwritten. Also a warning message is printed if the current pin is being
overwritten before abort.
This also avoids pin re-muxing to same type that is for example from
command line device is asked to re-probe/select (mmc dev x) we return
early with success in this case as the pin is already muxed.
