Fix unused variable warning in rockchip's rk_spi.c

Browse Source 
With clang 15, the following -Werror warning is produced:

    sys/arm64/rockchip/rk_spi.c:229:6: error: variable 'cnt' set but not used [-Werror,-Wunused-but-set-variable]
            int cnt = 0;
                ^

The 'cnt' variable was in rk_spi.c when it was first added, but it
appears to have been a debugging aid that has never been used, so remove
it.
