ARM: OMAP2+: hwmod data: split omap2/3 dispc hwmod class
Currently OMAP2 and 3 share the same omap_hwmod_class and
omap_hwmod_class_sysconfig for dispc. However, OMAP3 has sysconfig
bits that OMAP2 doesn't have, so we need to split those structs into
OMAP2 and OMAP3 specific versions.
This patch only splits the structs, without changing the contents.
This is a prerequisite for a subsequent fix.

ARM: OMAP: HWMOD: Unify DSS resets for OMAPs
This patch adds a custom DSS reset function used on OMAPs from OMAP2
forward.
The function doesn't actually do a reset, it only waits for the reset to
complete. The reason for this is that on OMAP4 there is no possibility
to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets
all the other DSS modules also, thus breaking the HWMOD model where
every DSS module is handled independently.
This fixes the problem with DSS reset on OMAP4, caused by the fact that
because there's no SW reset for dss_core on OMAP4, the HWMOD framework
doesn't try to reset dss_core and thus the DSS clocks were never enabled
at the same time. This causes causes the HWMOD reset to fail for
dss_dispc and dss_rfbi.
The common reset function will also allow us to fix another problem in
the future: before doing a reset we need to disable DSS outputs, which
are in some cases enabled by the bootloader, as otherwise DSS HW seems
to get more or less stuck, requiring a power reset to recover.

ARM: OMAP2/3: HWMOD: Add SYSS_HAS_RESET_STATUS for dss
OMAP2/3 dss_core has a reset status flag in sysstatus register. Add
SYSS_HAS_RESET_STATUS flag to HWMOD data so it can be used.
