v7a: tf-a: update to v2.4

Trusted Firmware-A v2.4 was released last month and adds amongst others,
enhancements to make use of the trusted boot chain possible with
upstream components.

The patch stack has now been posted upstream in hope we can eventually
drop it:
https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/7339
https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/7340

For now, it was rebased with following modifications:
  - Sync with upstream device tree and new TF-A requirements
  - CLK_ETH_PLL4P is enabled for possible PTP use

+Subject: [PATCH] fdts: stm32mp1: add support for Linux Automation MC-1 board
+
+The Linux Automation MC-1 is a SBC built around the Octavo Systems
+OSD32MP15x SiP. The SiP features up to 1 GB DDR3 RAM, EEPROM and
+PMIC. The board has eMMC and a SD slot for storage.
+
+The SDRAM calibration values are taken as is from the DKx boards, which
+seem to be suitable for operation at German room temperature.
+
+This is deemed ok for now, but for use in the field, the SiP will likely
+need to have its timings determined in a climate chamber.
