In contrast to variables, functions don't need extern declarations. It is
also preferred in the kernel not to use extern in front of function
declarations.
The extern+static parts in clk-rtl83xx.c were skipped because they are a
little bit unexpected ("extern *_dram_set_rate" are never used, "static
_sram_set_rate" are used but should from the C code perspective always be
NULL). This is left for an interested reader with the correct test HW and
some interests to dig in the code from commit 4850bd887c ("realtek: add
RTL83XX clock driver") for the *_dram_set_rate -> *_sram_set_rate
relocation and how these SRAM function pointers are set in this translation
unit.
