driver-core: Introduce DEVICE_ATTR_ADMIN_{RO,RW}
A common pattern for using plain DEVICE_ATTR() instead of
DEVICE_ATTR_RO() and DEVICE_ATTR_RW() is for attributes that want to
limit read to only root. I.e. many users of DEVICE_ATTR() are
specifying 0400 or 0600 for permissions.
Given the expectation that CAP_SYS_ADMIN is needed to access these
sensitive attributes and an explicit helper with the _ADMIN_ identifier
for DEVICE_ATTR_ADMIN_{RO,RW}.
