smc_api: Fix compilation issues (#40)

Browse source 
* smc_api: Add missing includes

MASTERKEY_REVISION_400_CURRENT, seal_titlekey, PMC_BASE and the randomcache functions  aren't visible without them

* smc_api: Add missing parameter name to smc_get_result

* smc_api: Fix buffer being passed to se_get_exp_mod_output in smc_unwrap_rsa_oaep_wrapped_titlekey_get_result

wrapped_titlekey doesn't exist

* smc_api: Correct device physical address accesses in smc_read_write_register
