efi/serial: re-init serial after efi detatchment

* This prevents haiku from "messing" with the gUART until
EFI boot services are exiting.
* The previous design meant that our loader started fiddling
with the gUART while EFI BIOS services were still being
used. On the SiFive, this broke serial output.
* Now, we guard on serial_init if EFI is unavailable, and
only fallback to direct UART usage when EFI is no longer
available.
* tldr; we're more closely managing serial across architectures
* serial_init use EFI and init it
* kernel_serial_handoff, stop using EFI
* serial_init, oh no EFI. Use gUART and Init it
* one gap is likely if no serial is available in EFI, but I
haven't seen that yet.

cpu: Extract shared x86 code from efi & bios_ia32

This issue was initially detected by PVS Studio (issue number V547) and fixed
as part of Google Code-in 2019.

The initial problem was the calculate_cpu_conversion_factor function
which had been copied in the BIOS and EFI versions of the boot code.
Further investigation led to more duplicated or very similar functions
being identified.

Introduce an arch_cpu.h for the x86 boot platform to group these things
in a single place, and adjust the BIOS and EFI code to call into that.
Note that the BIOS and EFI code is still a little platform specific,
ideally there should be a boot_arch_cpu_init() function for each
architecture as already done for openfirmware and u-boot.

Also remove some irrelevant comments from copypasted files for other
architectures, as that was filling my git grep with useless noise.
