Hi folks,

This series fixes support for correctly saving and restoring fltcon0
and fltcon1 registers on gs101 for non-alive banks where the fltcon
register offset is not at a fixed offset (unlike previous SoCs).
This is done by adding a eint_fltcon_offset and providing GS101
specific pin macros that take an additional parameter (similar to
how exynosautov920 handles it's eint_con_offset).

Additionally the SoC specific suspend and resume callbacks are
re-factored so that each SoC variant has it's own callback containing
the peculiarities for that SoC.

Finally support for filter selection on alive banks is added, this is
currently only enabled for gs101. The code path can be excercised using
`echo mem > /sys/power/state`

regards,

Peter
