mkbp_event,include/config.h: Clarify MKBP delivery method.
Now we have two MKBP delivery methods:
1. define CONFIG_MKBP_USE_HOST_EVENT to notify via host event
2. undef CONFIG_MKBP_USE_HOST_EVENT to notify via GPIO interrupt
It may become more complicated if new notification methods introduced.
e.g.: mt_scp uses IPI, rather than host event and GPIO interrupt.
This CL does:
1. add CONFIG_MKBP_USE_GPIO to explicilty declare that MKBP event are
sent via GPIO interrupt.
2. CONFIG_MKBP_USE_CUSTOM for boards which have custmized methods.
3. Remove weak attribute in mkbp_set_host_active (which can be done
with CONFIG_MKBP_USE_CUSTOM now.
4. Removes mkbp_set_host_active function in board Nocturne. It only
deliver MKBP events through GPIO interrupt now.
BRANCH=None
BUG=b:120808999
TEST=grep -rn "CONFIG_MKBP_USE_GPIO\|EC_INT_L" board/ baseboard/ and
see the result is reasonable:
1. EC_INT_L must be 1-to-1 mapped to define CONFIG_MKBP_USE_GPIO in
every board, except that meep, yorp, ampton which are defined in
baseboard octopus.
2. undef CONFIG_MKBP_USE_GPIO in bip and casta, which use host
event, but also have baseboard octopus.
