[PATCH v2 0/9] Fix MMC properties on Sitara devices

This patch series aims to update MMC nodes for TI 
K3 Sitara devices.

The series introduces MMC0 and MMC2 nodes and enables
eMMC for AM62ax platform.

Also introduce fixes for MMC ITAP/OTAP values for AM64x
platform according to device datasheet [0], and add ITAP/
OTAP values for AM62p to enable the highest timing possible
for MMC0 and MMC1, according to device datasheet [1].

The DLL properties ti,trm-icp and ti,driver-strength-ohm
should be removed for devices with soft PHYs since drive
strength cannot be changed, so remove these properties when
not applicable. Since this fix touches non-TI boards and
therefore cannot be tested, all tested-by's are welcome.

Also include a few fixes for ti,clkbuf-sel, bus-width,
and bootph-all device tree properties in MMC nodes.

This series was tested on:
- AM62a SK
- AM62x SK
- AM62p SK
- AM64x GP EVM
- AM64x SK EVM
- Beagleplay
