Subject: [RE-RESEND PATCH v3 3/4] memory: jz4780-nemc: Reduce size of const array

The maximum value found in that array is 15, there's no need to store
these values as uint32_t, a uint8_t is enough.

Signed-off-by: Paul Cercueil <paul@...pouillou.net>

Notes:
    v2: Remove casts to uint32_t
    
    v3: No change
