Fix compiler warning:

drivers/serial/ns16550.c: In function ‘serial_in_dynamic’:
drivers/serial/ns16550.c:153:1: warning: control reaches end
     of non-void function [-Wreturn-type]
   153 | }
       | ^

Observed with gcc 15.2.1:

$ riscv64-unknown-linux-gnu-gcc --version
riscv64-unknown-linux-gnu-gcc (Gentoo 15.2.1_p20260214 p5) 15.2.1


We also have another one in ns16550_readb that'll trigger the same 
warning I'm assuming. Ditto for ns16550_serial_pending.

Cheers,
Quentin
