a86854d0c5 treewide: devm_kzalloc() -> devm_kcalloc() 
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

        devm_kzalloc(handle, a * b, gfp)

with:
        devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

The comment block explaining the rationale for static pins contains
grammar errors.  It appeared first in the pin control driver for R-Car
H3 ES1.x, and spread to R-Car M3-W, H3 ES2.0, and M3-N later.

Fix the grammar in all copies at once.

Pull pin control bulk updates from Linus Walleij:
 "New drivers:

   - Qualcomm SDM845: this is their new flagship SoC platform which
     seems to be targeted at premium mobile handsets.

   - Renesas R-Car M3-N SoC.

   - Renesas R8A77980 SoC.

   - NXP (ex Freescale) i.MX 6SLL SoC.

   - Mediatek MT2712 SoC.

   - Allwinner H6 SoC.

  Improvements:

   - Uniphier adds a few new functions and pins.

   - Renesas refactorings and additional pin definitions.

   - Improved pin groups for Axis Artpec6.

  Cleanup:

   - Drop the TZ1090 drivers. This platform is no longer maintained and
     is being deleted.

   - Drop ST-Ericsson U8540/U9540 support as this was never
     productified.

   - Overall minor fixes and janitorial"

The pin controller drivers for all R-Car Gen2 SoCs have entries for the
EtherAVB TX_ER pins in their EtherAVB MII groups, except on R-Car H2.

Add the missing pin to restore consistency.

Note that technically TX_ER is an optional signal in the MII bus, and
thus could have its own group, but this is currently not supported by
any R-Car Gen2 pin controller driver.

625504aeff pinctrl: sh-pfc: r8a7795: remove duplicate of CLKOUT pin in pinmux_pins[] 
When adding GP-1-28 port pin support it was forgotten to remove the
CLKOUT pin from the list of pins that are not associated with a GPIO
port in pinmux_pins[]. This results in a warning when reading the
pinctrl files in sysfs as the CLKOUT pin is still added as a none GPIO
pin. Fix this by removing the duplicated entry which is no longer
needed.
