driver: crypto: SHA: npcx: fix SHA driver for npcx4 QS chip

Browse Source 
The commit fixes the SHA driver because the ROM API has the following
changes from ES to QS chip:
1. base addres: from 0x13c -> 0x148
2. required SHA context buffer size : from 228 -> 240 bytes

This change also adds a check for the pre-allocated buffer size of the
SHA context when the driver initiliazes.
