On Exynos5250, the FALL interrupt related en, status and clear bits are
available at an offset of
16 in INTEN, INTSTAT registers and at an offset of
12 in INTCLEAR register.
On Exynos5420, the FALL interrupt related en, status and clear bits are
available at an offset of
16 in INTEN, INTSTAT and INTCLEAR registers.
On Exynos5440,
the FALL_IRQEN bits are at an offset of 4
and the RISE_IRQEN bits are at an offset of 0
This patch introduces a new bit field intclr_fall_shift to handle the
offset for exyns5250 and exynos5440
