fix(plat/st): correct BSEC error code management
BSEC services should return SMC error codes as other IDs (defined in
stm32mp1_smc.h) and not BSEC driver ones. So that non-secure caller
is able to treat them correctly.
In global SMC handler, unknown ID should also return a value from this
definition list, and not the generic one, which seems not well adapted
for our needs.
Two unsigned values initializations are also changed from 0 to 0U.
