Hi,
This patch is a bit crude, but gets the job done. In a well designed
system this might even be good enough since
that the function is not implemented. Of all the other defined error
codes, the least bad is FFA_RET_INVALID_PARAMETERS, so use that instead.

Moves the two helper functions regpair_to_uint64() and
uint64_to_regpair() from xen/arch/arm/tee/optee.c to the common arm
specific regs.h. This enables reuse of these functions in the FF-A
mediator in a subsequent patch.

Adds support for sending a FF-A direct request. Checks that the SP also
supports handling a 32-bit direct request. 64-bit direct requests are
not used by the mediator itself so there is not need to check for that.
