[PATCH v2] parisc: Use asm-generic/serial.h

[Thorsten Blum <thorsten.blum@linux.dev>]

asm/serial.h only redefines BASE_BAUD with the same value as
asm-generic/serial.h. Select the generic header from Kbuild and remove
the arch-specific header.

Suggested-by: Helge Deller <deller@gmx.de>
Signed-off-by: Thorsten Blum <thorsten.blum@linux.dev>

Changes in v2:
- Delete the header and use Kbuild instead as suggested by Helge
- Reword subject and patch description
- v1: https://lore.kernel.org/r/20260804132051.104647-4-thorsten.blum@linux.dev/
