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.

As pointed by [1] and [2], commit
d64b9cdcd4 ("fdt: translate address if #size-cells = <0>") is wrong:
- It makes every 'reg' DT property translatable. It changes the address
translation so that for an I2C 'reg' address you'll get back as reg
the I2C controller address + reg value.
- The quirk must be fixed with platform code.
The clk_ti_get_reg_addr() is the platform code able to make the correct
address translation for the AM33xx clocks registers. Its implementation
was inspired by the Linux Kernel code.

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.

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.
For DT binding details see:
