Pull xtensa fixes from Max Filippov:

 - fix ccount_timer_shutdown for secondary CPUs

 - fix secondary CPU initialization

 - fix secondary CPU reset vector clash with double exception vector

 - fix present CPUs when booting with 'maxcpus' parameter

 - limit possible CPUs by configured NR_CPUS

 - issue a warning if xtensa PIC is asked to retrigger anything other
   than software IRQ

 - fix masking/unmasking of the first two IRQs on xtensa MX PIC

 - fix typo in Kconfig description for user space unaligned access
   feature

 - fix Kconfig warning for selecting BUILTIN_DTB
