Hardware Manual Errata for rev. 1.50 of March 26, 2019 removed the bit
definitions for MMC_CD and MMC_WP in the documentation for the IPSR6 and
IPSR7 registers, as these pin functionalities do not exist on R-Car
V3M.
Remove the definitions, and the corrresponding pins and groups.

There are two variants of the CPU_ALL_PORT() macro in use:
1. A three-parameter variant, to be provided for SoCs with a linear
GPIO pin space ("PORT style"),
2. A two-parameter variant, to be provided for SoCs with 32-port GPIO
banks ("GP port style").
Rename the 2-parameter variant to CPU_ALL_GP(), to avoid confusion, and
to increase naming consistency.

According to the R-Car Gen3 Hardware Manual Errata for Rev 1.50 of
Feb 12, 2019, the RTS{0,1,3,4}_#/TANS pin names defined in the GPSR and
IPSR registers are renamed to RTS{0,1,3,4}_#.
This patch updates the pin control drivers to reflect this.

Currently the PINMUX_CFG_REG_VAR() macro must be followed by
initialization data, specifying all enum IDs. Hence the macro itself
does not know anything about the enum IDs, preventing the macro from
performing any validation on it.
Make the macro accept the enum IDs as a parameter, and update all users.
Note that array data enclosed by curly braces cannot be passed to a
macro as a parameter, hence both the register field widths and the enum
IDs are wrapped using the GROUP() macro.
No functional changes.

Source files using -Exxx error codes should include <linux/errno.h>.
On ARM, this header file is included indirectly; on SuperH, it is not,
leading to "error: ‘EINVAL’ undeclared" failures when enabling
compile-testing later.

The R-Car Gen3 HardWare Manual Errata for Rev. 1.00 (Jul 2, 2018)
renamed the various miscellaneous I/O control registers (IOCTRLx) on
R-Car V3M, to reflect better their actual purposes, and matching other
SoCs.
Update the code to match this.

The datasheet does not document any registers to control drive strength,
and no drive strength registers are for this reason described for this
SoC. The flags indicating that drive strength can be controlled are
however set for some pins in the driver.
This leads to a NULL pointer dereference when the sh-pfc core tries to
access the struct describing the drive strength registers, for example
when reading the sysfs file pinconf-pins.
Fix this by removing the SH_PFC_PIN_CFG_DRIVE_STRENGTH from all pins.
