ARM: SAMSUNGy: fix broken timer irq base

Timer interrupts range was defined as 43-47, what overlaps with VIC0 range
(32-64). This was caused probably by a typo while the common interrupts
definition was refactored. This patch moves timer interrupt range to safe
area of 11-15 (just before uart range).

This fixes the commit 87aef30eb3c5dac0491c83fe3b90bc61f1df24ec
("ARM: S5P: Change S5P_TIMER_IRQ based to 11 for SAMSUNG S5P series.")
which meant to move these into the old (and previously reserved)
ISA space.
