To avoid having an exact copy of this struct for gs101 rename it and use it
for both SoCs for eint banks.
The purpose of this for exynosautov920 and gs101 is to obtain the PMU
syscon for writing the calculated WAKEUP_MASK register(s).

gs101 differs to other SoCs in that fltcon1 register doesn't
always exist. Additionally the offset of fltcon0 is not fixed
and needs to use the newly added eint_fltcon_offset variable.

Refactor the existing platform specific suspend/resume callback
so that each SoC variant has it's own callback containing the
SoC specific logic.
This allows exynosautov920 to have a dedicated function for using
eint_con_offset and eint_mask_offset. Also it is easily extendable
for gs101 which will need dedicated logic for handling the varying
register offset of fltcon0 via eint_fltcon_offset.

On gs101 SoC the fltcon0 (filter configuration 0) offset isn't at a
fixed offset like previous SoCs as the fltcon1 register only exists when
there are more than 4 pins in the bank.
Add a eint_fltcon_offset and new GS101_PIN_BANK_EINT* macros that take
an additional fltcon_offs variable.
This can then be used in suspend/resume callbacks to save and restore
the fltcon0 and fltcon1 registers.

GPIO_ALIVE and GPIO_CMGP blocks in Exynos850 SoC don't have EINT
capabilities (like EINT_SVC register), and there are no corresponding
interrupts wired to GIC. Instead those blocks have wake-up interrupts
for each pin. The ".eint_gpio_init" callbacks were specified by mistake
for these blocks, when porting pinctrl code from downstream kernel. That
leads to error messages like this:
samsung-pinctrl 11850000.pinctrl: irq number not available
Remove ".eint_gpio_init" for pinctrl_alive and pinctrl_gpmc to fix this
error. This change doesn't affect proper interrupt handling for related
pins, as all those pins are handled in ".eint_wkup_init".

Driver uses alias from Device Tree as an index of pin controller data
array. In case of a wrong DTB or an out-of-tree DTB, the alias could be
outside of this data array leading to out-of-bounds access.
Depending on binary and memory layout, this could be handled properly
(showing error like "samsung-pinctrl 3860000.pinctrl: driver data not
available") or could lead to exceptions.

Exynos pinctrl drivers contain pretty big per-SoC data structures. The
pinctrl-exynos object file contained code and data for both ARMv7 and
ARMv8 SoCs thus it grew big. There will not be a shared image between
ARMv7 and ARMv8 so there is no need to combine all of this into one
driver.
Splitting the data allows to make it more granular (e.g. code related to
ARMv8 Exynos is self-contained), slightly speed up the compilation and
reduce the effective size of compiled kernel.
The common data structures and functions reside still in existing
pinctrl-exynos.c. Only the SoC-specific parts were moved out to new
files. Except marking few functions non-static and adding them to
header, there were no functional changes in the code.
