Subject: [PATCH v2 08/10] ARM: OMAP1: Get rid of <mach/ams-delta-fiq.h>
Split the header file into two parts and move them to directories where
they belong.
Information on internal structure of FIQ buffer is moved to
<linux/platform_data/ams-delta-fiq.h> for ams-delta-serio driver use.
Other information used by ams-delta board init file and FIQ code is
made local to mach-omap1 root directory.
Signed-off-by: Janusz Krzysztofik <jmkrzyszt@...il.com>

Changelog:
v2: rebased on v4.18-rc1, no conflicts
