5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stephan Gerhold <redacted>

commit c5339edc6abb601ea10df910ea0b1592fa1016f3 upstream.

According to the APQ8016E TRM, 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).
