Commit da040d560319 ("dt-bindings: clock: qcom: gcc-ipq9574: remove q6
bring up clock macros") removed these clocks on the idea that Q6
firmware is responsible for clock bringup. That statement seems
incorrect, as these clocks need to be enabled before the Q6 is booted.
Otherwise, the host CPU core that starts the Q6 hangs.
Perhaps the statement meant that the TrustZone firmware will start the
clocks. This only happens in PAS mode. Under native OS loading, the
host needs these clocks, so add them back.
Besides the clocks that were erroneously removed, also add defines for
GCC_WCSS_AHB_S_CLK, GCC_WCSS_AXI_M_CLK, and GCC_Q6_AXIM2_CLK, as all
these clocks are required to operate the remoteproc.
