POPS: Boot converted PBPs with firmware 4.05

The user modules started after the manager now come from the firmware's
own boot configuration (pspbtcnf.bin's POPS mode), since they differ by
version: 4.05's pafmini.prx needs heaparea2.prx first. 6.60's also
lists common_util.prx, which wasn't started before.

4.05 renumbered the kernel NIDs again. Its aliases are checked like
5.55's, and the sysreg ones by what they do to the registers: the call
sites got five of those wrong. Its manager allocates from a pool with
the kernel's sceKernelAllocateFpl, which stays unresolved for kernel
modules (see ThreadManForKernel), so only the manager's import gets the
user one. scePower_driver gets 6.60's clock frequency NID, which 6.20's
and 4.05's old one now map to.
