ARM: 8089/1: cpu_pj4b_suspend_size should base on cpu_v7_suspend_size
Since pj4b suspend/resume routines are implemented based on generic ARMv7 ones, instead of hard-coding cpu_pj4b_suspend_size, we should have it be cpu_v7_suspend_size plus pj4b specific bytes. Otherwise, if cpu_v7_suspend_size gets updated alone, the pj4b suspend/resume will likely be broken. While at it, fix the comments in cpu_pj4b_do_resume, as we're restoring CP15 registers rather than saving in there.
