This patch adds a new struct pwrap_slv_type that we use to store the slave
specific data. The patch adds 2 new helper functions to access the dew
registers. The slave type is looked up via the wrappers child node.

Comparing with the implementation of MT6323, the following registers
seem MT6397 only:
PWRAP_DEW_EVENT_OUT_EN
PWRAP_DEW_EVENT_SRC_EN,
PWRAP_DEW_EVENT_SRC
PWRAP_DEW_EVENT_FLAG
PWRAP_DEW_MON_FLAG_SEL
PWRAP_DEW_EVENT_TEST
PWRAP_DEW_CIPHER_LOAD
PWRAP_DEW_CIPHER_START
Can you please check that and put the ones which are really MT6397 only
in a separate paragraph?
Thanks,
Matthias
