Introduce CONFIG_PHYTEC_K3_DDR_PATCH to make DDR timing patch code
optional for PHYTEC K3 boards. This allows better control over which
boards receive DDR timing patches, rather than compiling the code for
all boards with K3_DDRSS enabled.
Also enable the feature by default for PHYCORE_AM62X_R5.

AM62x devices now support CPU throttling based on thermal alerts
with a Linux commit 10e7bfd8114c ("arm64: dts: ti: k3-am62: Enable
CPU freq throttling on thermal alert"). However, this functionality
does not work correctly across all variants of the AM62x SoCs
which have different numbers of Cortex-A CPU cores: AM62x1 (1 core),
AM62x2 (2 cores), and AM62x4 (4 cores). On single-core and dual-core
AM62x devices, the following error is observed in the Linux kernel:
OF: /thermal-zones/main0-thermal/cooling-maps/map0: could not find
phandle 94
OF: /thermal-zones/main1-thermal/cooling-maps/map0: could not find
phandle 94
This commit adds a fixup to dynamically adjust the cooling-device
nodes in the thermal zones based on the actual number of CPU cores
available. This resolves the issue of CPU throttling not working
correctly on single-core and dual-core AM62x devices, while
maintaining the functionality for AM62x quad-core devices.
A similar approach is implemented for example on i.MX8MM SoC.

- update MAINTAINERS file

Move beagleplay support away from ti/am62x to it's own beagle vendor
folder.
This forms the starting point for new beagle platforms added under it's
own board vendor folder.
As part of this create all the associated files with a bare minimum
beagleplay.c file.

Currently each set of board targets from a vendor is selected inside
the board directory for that vendor. This has the problem of multiple
targets, one from each vendor, being selectable at the same time.
For instance you can select both TARGET_AM654_A53_EVM and
TARGET_IOT2050_A53 in the same build.
To fix this we need to move the target board choice to a common location
for each parent SoC selection. Do this in arch/arm/mach-k3.
