clk: ti: am3-dpll: use custom API for memory access
Using the custom TI functions required not only replacing common memory

of the register to be accessed, a parameter that is hidden by the TI clk

clk: ti: add custom API for memory access
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.

env: allow environment to be amended from control dtb
It can be useful to use the same U-Boot binary for multiple purposes,
say the normal one, one for developers that allow breaking into the
U-Boot shell, and one for use during bootstrapping which runs a
special-purpose bootcmd. Or one can have several board variants that
can share almost all boot logic, but just needs a few tweaks in the
variables used by the boot script.
To that end, allow the control dtb to contain a /config/enviroment
node (or whatever one puts in fdt_env_path variable), whose
property/value pairs are used to update the run-time environment after
it has been loaded from its persistent location.
The indirection via fdt_env_path is for maximum flexibility - for
example, should the user wish (or board logic dictate) that the values
in the DTB should no longer be applied, one simply needs to delete the
fdt_env_path variable; that can even be done automatically by
including a
fdt_env_path = "";
property in the DTB node.
