8250/fintek: rename IRQ_MODE macro
A bugfix for the fintek driver required defining some macros, but
one of them clashes with a system header on ARM:
drivers/tty/serial/8250/8250_fintek.c:34:0: error: "IRQ_MODE" redefined [-Werror]
#define IRQ_MODE 0x70

arch/arm/include/uapi/asm/ptrace.h:55:0: note: this is the location of the previous definition
This renames the newly introduced 'IRQ_MODE' macro to FINTEK_IRQ_MODE.
