[PATCH 3/3] lib: sbi: dbtr: return SBI_ERR_INVALID_PARAM for invalid trigger configuration

[David E. Garcia Porras]

sbi_dbtr_install_trig() returns the generic SBI_ERR_FAILED when
dbtr_trigger_valid() rejects a trigger configuration (dmode or M-mode
bits set), where SBI v3.0 section 19.4 defines SBI_ERR_INVALID_PARAM
for an invalid trigger configuration entry. Return
SBI_ERR_INVALID_PARAM instead.

Fixes: 97f234f15c96 ("lib: sbi: Introduce the SBI debug triggers extension support")
