Subject: b4aa54d951d38d7a989d6b6385494ef5ea7371d7 breaks some serial configurations

The above commit contains the following patch:

The code between these two hunks contains the following:

| #ifdef CONFIG_SERIAL_8250_DETECT_IRQ
| #define CONFIG_SERIAL_DETECT_IRQ 1
| #endif
| #ifdef CONFIG_SERIAL_8250_MANY_PORTS
| #define CONFIG_SERIAL_MANY_PORTS 1
| #endif

and asm-*/serial.h contains:

| $ grep 'CONFIG_SERIAL_DETECT\|CONFIG_SERIAL_MANY' include/asm-*/serial.h
| include/asm-alpha/serial.h:#ifdef CONFIG_SERIAL_DETECT_IRQ
| include/asm-m68k/serial.h:#ifdef CONFIG_SERIAL_DETECT_IRQ

| include/asm-mn10300/serial.h:#ifdef CONFIG_SERIAL_MANY_PORTS
| include/asm-x86/serial.h:#ifdef CONFIG_SERIAL_DETECT_IRQ

So, all these ifdefs are now useless.
