soc/amd/common/psp_smm: introduce and use send_psp_command_smm

When sending mailbox commands to the PSP from SMM, the SMM flag needs to
be set right before sending the mailbox command and cleared right after
the command is sent. In order to not have this code duplicated, factor
it out into a function.
