Add BRANCH_HALT_VOTED flag to inform clock framework don't check for CLK_OFF bit. CRYPTO_AHB_CLK_ENA and CRYPTO_AXI_CLK_ENA enable bit is present in other VOTE registers also, like TZ. If anyone else also enabled this clock, even if we turn off in GCC_APCS_CLOCK_BRANCH_ENA_VOTE | 0x180B004, it won't turn off.
