ARM: OMAP1: ams-delta: Fix impossible .irq < 0
Since the very beginning, unsigned int .irq member of struct
plat_serial8250_port introduced by commit eff443df679e ("OMAP1:
AMS_DELTA: add modem support") was statically initialized to a negative
value -EINVAL. Moreover, commit 0812db943748 ("ARM: OMAP1: ams-delta:
assign MODEM IRQ from GPIO descriptor") has introduced some new code
which checks for that member carrying a negative value which is
impossible.
Use IRQ_NOTCONNECTED instead of -EINVAL. Also, drop the valueless check
and let the modem device be registered regardless of .irq value, and
the value handled by "serial8250" driver.
Fixes: 0812db943748 ("ARM: OMAP1: ams-delta: assign MODEM IRQ from GPIO descriptor")
