arm: kernel: Add SMC structure parameter

This patch adds a quirk parameter to the arm_smccc_smc call.  The quirk
structure allows for specialized SMC operations due to SoC specific
requirements.

This patch also fixes up all the current users of the arm_smccc_smc API.

This patch and partial implementation was suggested by Will Deacon.
