firmware: qcom: scm: Drop cpumask parameter from set_boot_addr()
qcom_scm_set_cold/warm_boot_addr() currently take a cpumask parameter,
but it's not very useful because at the end we always set the same entry
address for all CPUs. This also allows speeding up probe of
cpuidle-qcom-spm a bit because only one SCM call needs to be made to
the TrustZone firmware, instead of one per CPU.
The main reason for this change is that it allows implementing the
"multi-cluster" variant of the set_boot_addr() call more easily
without having to rely on functions that break in certain build
configurations or that are not exported to modules.
