Subject: [PATCH -next] hwrng: cctrng - Make some symbols static

Fix the following sparse warnings:

drivers/char/hw_random/cctrng.c:316:6: warning: symbol
'cc_trng_compwork_handler' was not declared. Should it be static?
drivers/char/hw_random/cctrng.c:451:6: warning: symbol
'cc_trng_startwork_handler' was not declared. Should it be static?
