Add driver to support TI K3 generation SoC clocks. This driver registers
the clocks provided via platform data, and adds support for controlling
the clocks via DT handles.

Add support for TI K3 SoC PLLs. This clock type supports
enabling/disabling/setting and querying the clock rate for the PLL. The
euclidean library routine is used to calculate divider/multiplier rates
for the PLLs.

Set rate should return the new clock rate on success, and negative error
value on failure. Fix this, as currently set_rate returns 0 on success.

Using the custom TI functions required not only replacing common memory
access functions but also rewriting the routines used to set bypass and
lock states. As for readl() and writel(), they also required the address
of the register to be accessed, a parameter that is hidden by the TI clk
module.

Replaces the common memory access functions used by the driver with the
ones exported from the TI clk module.

The clock access functions exported by the clk header use the
struct clk_ti_reg parameter to get the address of the register. This
must also apply to clk_ti_latch(). Changes to TI's clk-mux and
clk-divider drivers prevented the patch from generating compile errors.

The previous version printed the same debug message for both the enable
and disable routines without highlighting whether you were enabling or
disabling the module. It is now clear whether you are enabling or
disabling the module.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

Something was wrong in the merge process into the mainline.
Some added patches access driver structure fields and functions that
have been modified by previous patches.
The patch renames:
- dev_get_platdata to dev_get_plat
- dev_get_uclass_platdata to dev_get_uclass_plat
- ofdata_to_platdata to of_to_plat
- plat_data_alloc_size to plat_auto
- priv_auto_alloc_size to priv_auto
- video_uc_platdata to video_uc_plat

The patch moves the clk-ti-sci.c file to the 'ti' directory along with
all the other TI's drivers, and renames it clk-sci.c.

Until now the clkctrl clocks have been enabled/disabled through platform
routines. Thanks to this patch they can be enabled and configured directly
by the probed devices that need to use them.

The patch adds support for TI gate clock binding. The code is based on
the drivers/clk/ti/gate.c driver of the Linux kernel version 5.9-rc7.

The patch adds support for TI divider clock binding. The driver uses
routines provided by the common clock framework (ccf).
The code is based on the drivers/clk/ti/divider.c driver of the Linux
kernel version 5.9-rc7.

The digital phase-locked loop (DPLL) provides all interface clocks and
functional clocks to the processor of the AM33xx device. The AM33xx
device integrates five different DPLLs:
* Core DPLL
* Per DPLL
* LCD DPLL
* DDR DPLL
* MPU DPLL
The patch adds support for the compatible strings:
* "ti,am3-dpll-core-clock"
* "ti,am3-dpll-no-gate-clock"
* "ti,am3-dpll-no-gate-j-type-clock"
* "ti,am3-dpll-x2-clock"
The code is loosely based on the drivers/clk/ti/dpll.c drivers of the
Linux kernel version 5.9-rc7.

The driver manages a register-mapped multiplexer with multiple input
clock signals or parents, one of which can be selected as output. It
