Merge branch 'staging' of https://source.denx.de/u-boot/custodians/u-boot-tegra into next

This PR contains 4 patchsets:

1. PMIC GPIO cells bringup. Created drivers for MAX7663 and Palmas
PMICs and gpio-uclass patch isolated behind configs for these 2
drivers. No unintentional size increase on any board. (proposed
2023-11-06 without any reaction)

2. Simple PLL clocks support in common tegra clock code which allows
use of simple PLL the same way main PLLs are used (before only
clock_start_pll was available). PLLD2 is an example of simple PLL, it
is used as a video subsystem parent clock and was used to test this
code. So far everything worked as expected. (proposed 2023-11-16
without any reaction)

3. A small patch for tegra emmc to allow pass max frequency from
device tree since some devices may not support full speed.

4. Pinmux DM conversion. Patchset consists of commit with DM wrapper
for existing pinmux code for t20/t30/t114, pinmux and funcmux files
relocation into a dedicated folder inside pinctrl, conversion of some
tegra boards to device tree pinmux setup.
