BCM2711 has different pull-up/down register values compared to BCM2835

- BCM2835: NONE=0, DOWN=1, UP=2
- BCM2711: NONE=0, UP=1, DOWN=2

This patch fixes the pull state register values for BCM2711.

The hardware denies any access from the U-Boot non-secure world to the
secure-protected pins. Hence, prevent any driver to configure such a pin.
Identify the secure pins with "NO ACCESS" through the 'pinmux status -a'
command.
Use a driver data structure to identify which hardware versions support
this feature.

Replace uclass_get_device_by_ofnode() with syscon_regmap_lookup_by_phandle()
to get the "mediatek,pctl-regmap" syscon device.

Depending on probe order, uclass_get_device_by_ofnode() may fail, but
syscon_regmap_lookup_by_phandle() has logic in it to handle that case
correctly.

The previous implementation could read more than one syscon if the
"mediatek,pctl-regmap" property had more than one phandle, but the one
board with a devicetree that does that is not supported in U-Boot yet,
so we can save that for later (it may never be needed).

Ignore the error return value from mtk_pinconf_bias_set_pupd_r1_r0().
The PUPD/R1/R0 registers only include a small subset of the pins, so
it is normal for this function to return an error for most pins.
Therefore, this error should not be propagated.

This fixes not all pins in a pinmux group being configured in some
cases because the propagated error caused the configuration loop to
exit early.

The rest of the function is refactored to return early on errors to
improve readability.

Set the size of the reg_cals arrays to PINCTRL_PIN_REG_MAX to in all
affected mediatek pinctrl drivers. This is needed to avoid potential
out-of-bounds accesses when they is used in mtk_hw_pin_field_get().
All array members need to be initialized since the code loops from 0
to PINCTRL_PIN_REG_MAX - 1. mt7622_reg_cals was already defined this
way, but the others were not.

Introduce a new Kconfig option PINCTRL_QCOM_GENERIC that, when selected,
enables all Qualcomm pinctrl drivers by default. This simplifies defconfigs
for platforms supporting multiple SoCs and avoids manual driver selection.
Individual drivers can still be disabled if required.
