Subject: [PATCH] staging: ccree: remove unused pointer cc_base

From: Colin Ian King <colin.king@...onical.com>

Pointer cc_base is being assigned but is never read, hence it is
redundant and can be removed. Cleans up clang warning:

drivers/staging/ccree/ssi_driver.c:235:2: warning: Value stored to
'cc_base' is never read
