Linus reports that some Renesas pin control sub-drivers are still
including <linux/gpio.h> instead of <linux/gpio/driver.h>. As these
sub-drivers don't need either, the includes can just be removed.

The checker failed to validate all enum IDs in the description of a
register with fixed-width register fields, due to a miscalculation of
the number of described states: each register field of n bits can have
"1 << n" possible states, not "1".
Increase SH_PFC_MAX_ENUMS accordingly, now more enum IDs are checked
(SH-Mobile AG5 has more than 4000 enum IDs defined).
Fixes: 12d057bad6 ("pinctrl: sh-pfc: checker: Add check for enum ID conflicts")

Validate consistency of the pin control tables for pins with I/O voltage
capabilities. If a pin has I/O voltage register bits declarations
through .pin_to_pocctrl(), the SH_PFC_PIN_CFG_IO_VOLTAGE flag should be
set in the pin's configs, and vice versa.

Validate consistency of the pin control tables for pins with pull-up
and/or pull-down capabilities. If a pin has bias register bits
declarations in bias_regs[] or through .pin_to_portcr(), the
corresponding SH_PFC_PIN_CFG_PULL* flags should be set in the pin's
configs, and vice versa, and the .get_bias() and .set_bias() callbacks
should be implemented.

Currently rcar_pin_to_bias_reg() takes a struct sh_pfc pointer, which is
only available after the pin control driver has been initialized,
thus preventing the checker from calling this function for validating
consistency of the pin control tables.
Fix this by replacing the parameter by a struct sh_pfc_soc_info pointer.

All implementations of the .pin_to_portcr() method implement the same
conversion from Port Control Register offset to virtual address. Factor
it out into the two callers.
Remove the pfc parameter, as it is no longer used.
Note that the failure handling in r8a7740_pin_to_portcr() is pro forma,
as the function is never called with an invalid pin number.

The pfc parameter of the .pin_to_pocctrl() method was never used.
It is a relic of the old I/O voltage handling before commit
8775306dcf ("pinctrl: sh-pfc: refactor voltage setting").
Remove the parameter, as it prevents the checker from calling this
function for validating consistency of the pin control tables.
