[01/10] staging: wilc1000: sdio/spi: use device print api instead of custom one

Commit Message

Glen Lee Nov. 23, 2015, 9:47 a.m. UTC

This patch use device print api instead of driver defined print. Remove
varialbe dPrint as well. String "[wilc sdio]" and "[wilc spi]" are also removed
from all the print statment if exist because it shows which device the message
is related to.
