Use devm_of_iomap() instead of of_iomap() to automatically
handle the unused ioremap region. If any error occurs, regions allocated by
kzalloc() will leak, but using devm_kzalloc() instead will automatically
free the memory using devm_kfree().
Also, fix error handling of hws by adding unregister_hws label, which
unregisters remaining hws when iomap failed.

Randconfig testing revealed multiple issues with this driver:
ERROR: modpost: missing MODULE_LICENSE() in drivers/clk/imx/clk-imxrt1050.o
ERROR: modpost: "imx_clk_hw_pllv3" [drivers/clk/imx/clk-imxrt1050.ko] undefined!
ERROR: modpost: "imx_clk_hw_pfd" [drivers/clk/imx/clk-imxrt1050.ko] undefined!
Export the necessary symbols from the core clk driver and add the
license and author tags. To find this type of problem more easily
in the future, also enable building on other platforms, as we do for
the other i.MX clk drivers.

The imx_obtain_fixed_clk_hw name was wrong and misleading. Renaming it
to imx_get_clk_hw_by_name clarifies the purpose of the function, and
will allow it to be used not only for fixed rate clocks but also in
wider contexts.
No functional changes intended.
The replacements were made with the following command:
grep -rl 'imx_obtain_fixed_clk_hw' ./ | \
xargs sed -i 's/imx_obtain_fixed_clk_hw/imx_get_clk_hw_by_name/g'
Tested on a BSH SystemMaster (SMM) S2 board.
