mips: bcm63xx: add support for clk_get_parent()
[ Upstream commit e8f67482e5a4bc8d0b65d606d08cb60ee123b468 ]
BCM63XX selects HAVE_LEGACY_CLK but does not provide/support
clk_get_parent(), so add a simple implementation of that
function so that callers of it will build without errors.
Fixes these build errors:
mips-linux-ld: drivers/iio/adc/ingenic-adc.o: in function `jz4770_adc_init_clk_div':
ingenic-adc.c:(.text+0xe4): undefined reference to `clk_get_parent'
mips-linux-ld: drivers/iio/adc/ingenic-adc.o: in function `jz4725b_adc_init_clk_div':
ingenic-adc.c:(.text+0x1b8): undefined reference to `clk_get_parent'
Fixes: e7300d04bd08 ("MIPS: BCM63xx: Add support for the Broadcom BCM63xx family of SOCs." )
