> Several Exynos9-era pin-bank tables were implicitly assuming that the
> filter control (FLTCON) registers are laid out contiguously from the
> EINT base offset. Per the TRMs this is not always true. FLTCON can live
> at a separate per-bank offset, and the current tables cause the driver
> to program the wrong FLTCON addresses for some banks.

> - Extends EXYNOS9_PIN_BANK_EINTG()/EINTW() to take an explicit
>   .eint_fltcon_offset parameter.
> - Updates pin-bank tables with the correct FLTCON offsets for:
>   Exynos2200 (ALIVE/CMGP/HSI1/UFS/HSI1UFS/PERIC0/1/2/VTS),
>   Exynos7870 (ALIVE/DISPAUD/ESE/FSYS/MIF/NFC/TOP/TOUCH),
>   Exynos7885 (ALIVE/DISPAUD/FSYS/TOP),
>   Exynos850  (ALIVE/CMGP/AUD/HSI/CORE/PERI),
>   Exynos990  (ALIVE/CMGP/HSI1/HSI2/PERIC0/1/VTS),
>   Exynos9810 (ALIVE/AUD/CHUB/CMGP/FSYS0/FSYS1/PERIC0/1/VTS),
>   ExynosAuto v9 (ALIVE/AUD/FSYS0/1/2/PERIC0/1),
>   Exynos8890 (ALIVE/AUD/CCORE/ESE/FP/FSYS0/1/NFC/PERIC0/1/TOUCH),
>   Exynos8895 (ALIVE/ABOX/VTS/FSYS0/1/BUSC/PERIC0/1),
>   and FSD (FSYS/PERIC).
> 
> Notes:
> - GS101 already programs per-bank filter control registers. This change
>   aligns the Exynos9 path with that model.
> - Banks without filters (EINTN) are unaffected.
