psci: rework cpu_off assertion and minor cleanups
This patch:
1. removes a duplicate assertion to check that the only error
condition that can be returned while turning a cpu off is
PSCI_E_DENIED. Having this assertion after calling
psci_afflvl_off() is sufficient.
2. corrects some incorrect usage of 'its' vs 'it is'
3. removes some unwanted white spaces
