clk: qcom: gcc-msm8939: Fix enable_reg for gcc_blsp1_sleep_clk

Browse Source 
MSM8939 is similar to MSM8916, where the GCC_BLSP1_SLEEP_CBCR register is
read-only and only has the CLK_OFF bit to check if the clock is running.
This is a shared vote clock, the correct way to enable it is to vote for
BLSP1_SLEEP_CLK_ENA (BIT(9)) in GCC_APCS_CLOCK_BRANCH_ENA_VOTE (0x45004).
