watchdog: s3c2410_wdt: Fix PMU register bits for ExynosAutoV920 SoC

Fix the PMU register bits for the ExynosAutoV920 SoC.
This SoC has different bit information compared to its previous
version, ExynosAutoV9, and we have made the necessary adjustments.

rst_stat_bit:
    - ExynosAutoV920 cl0 : 0
    - ExynosAutoV920 cl1 : 1

cnt_en_bit:
    - ExynosAutoV920 cl0 : 8
    - ExynosAutoV920 cl1 : 8
