core: simplify pm_call usage
Simplify the pm_call usage:
- pm_call now saves and restores all registers
callees that want to return values in registers can mess with
the frame on the stack
- the PM function now enters with EAX = EBP = RM stack
(EAX for the use of C code, EBP for assembly)
- the RM stack frame matches com32sys_t
- pmcall.inc defined macros for the stack frame based on EBP
