kernel-yocto: restore BSP audit visibility

Browse Source 
During the re-working of kernel fragments and status output cleanup the
visibility for BSP level errors was dropped/removed.

The audit phase can detect errors, redefinition and invalid
configuration fragments. We control the visibility of these reports via
the existing KCONF_BSP_AUDIT_LEVEL variable.

By default, errors and invalid configuration values will be displayed as
a warning. If redefinition values are to be shown the audit level must
be raised above the deafult value of '2'. We inhibit these by default,
since there are many valid reasons why a BSP will change a default /
base config .. and showing them offers no value to the BSP user.
