Hi Volodymyr,

This patch adds generic definitions used in ARM SMC call convention.
Those definitions was taken from linux header arm-smccc.h, extended
and formatted according to XEN coding style. Some of the macros were
converted to inlined functions to ease parsing.
They can be used by both SMCCC clients (like PSCI) and by SMCCC
servers (like vPSCI or upcoming generic SMCCC handler).

* Accessor macros were converted to inlined functions
* ARM_SMCCC_SMC_{32,64} renamed to ARM_SMCCC_CONV_{32,64}
* Fixed indentation for ARM_SMCCC_CALL_VAL
