[S] Change in coreboot[main]: drivers/smmstore/ramstage: use call_smm

[Felix Held (Code Review)]

Hello build bot (Jenkins),

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/79766?usp=email

to look at the new patch set (#3).

Change subject: drivers/smmstore/ramstage: use call_smm
......................................................................

drivers/smmstore/ramstage: use call_smm

Use call_smm instead of open-coding the same in inline assembly
functionality in init_store. The local ebx variable is dropped, since
call_smm takes a pointer to the argument instead of an integer, and the
local eax variable is renamed to res to make the code a bit clearer,
since the EAX register is used for both passing the command and
subcommand to the APMC SMI handler and to get the return value from the
handler.
