Unlike (synchronous) exception handlers, interrupt handlers don't normally
have a need to know the outer context's register state. Similarly, the vast
majority of key handlers has no need for such.

1: serial: fake IRQ-regs context in poll handlers
2: keyhandler: drop regs parameter from handle_keyregs()
3: serial: drop serial_rx_fn's regs parameter
4: PV-shim: drop pv_console_rx()'s regs parameter
5: serial: drop serial_[rt]x_interrupt()'s regs parameter
6: IRQ: drop regs parameter from handler functions
7: x86/APIC: drop regs parameter from direct vector handler functions
8: consolidate do_bug_frame() / bug_fn_t
