leds: lp55xx: add common macros for device attributes
This patch provides common macros for LP5521 and LP5523 device attributes and
functions.
(Device attributes)
LP5521: 'mode', 'load' and 'selftest'
LP5523: 'mode', 'load', 'leds' and 'selftest'
(Permissions)
mode: R/W
load: Write-only
leds: R/W
selftest: Read-only
Couple of lines are duplicate, so use these macros for adding device attributes
in LP5521 and LP5523 drivers.
