clk: qcom: gcc-sdxpoorwills: change halt check for some PCIe clocks

The gcc_pcie_pipe_clk and gcc_pcie_aux_clk clocks are sourced
from external clocks inside of the PCIe PHY.  There is no
guarantee that these clocks are enabled after their parent or
that they are disabled before their parent.

Therefore, change the halt_check for these clocks to
BRANCH_HALT_DELAY so that the clock status bit is not polled
when enabling or disabling the clocks.  Such status checking
leads to unnecessary error logging and error return values.
