remoteproc: qcom_q6v5_pas: disable auto boot for wpss 



Currently, the rproc "atomic_t power" variable is incremented during:
a. WPSS rproc auto boot.
b. AHB power on for ath11k.

During AHB power off (rmmod ath11k_ahb.ko), rproc_shutdown fails
to unload the WPSS firmware because the rproc->power value is '2',
causing the atomic_dec_and_test(&rproc->power) condition to fail.

Consequently, during AHB power on (insmod ath11k_ahb.ko),
QMI_WLANFW_HOST_CAP_REQ_V01 fails due to the host and firmware QMI
states being out of sync.
