Subject: [PATCH V2 0/6] serial: 8250_fintek: Fix the IRQ mode and code refactoring

The following patches will fix the Fintek LPC to UARTs IRQ mode mismatch
issue and code refactoring.

Some BIOS only use _OSI("Linux") to distinguish between Linux & Windows.
Apply Level/Low to UART trigger mode if Windows, Edge/High otherwise.
But since 2.6.23 the mainline kernel no longer returns true for
_OSI("Linux"). The BIOS ASL should avoid to use _OSI() to check system
type and use ACPI MADT override IRQ mode instead.

We'll try to refactoring the source code more readable with SuperIO
read/write register functions.

Changelog:
V2
    1. Code refacting. Suggest by Ricardo Ribalda Delgado.
