clk: bm1800: Remove set but not used variable 'fref'

Browse Source 
Fixes gcc '-Wunused-but-set-variable' warning:

drivers/clk/clk-bm1880.c: In function 'bm1880_pll_rate_calc':
drivers/clk/clk-bm1880.c:477:13: warning:
 variable 'fref' set but not used [-Wunused-but-set-variable]

It is never used, so remove it.
