drivers/net/r8168: Add customized LED mode

Browse Source 
This patch adds a function to program a customized LED setting
for Realtek 81xx family. It reads the settings from devicetree under
target board and programs the setting to offset 0x18 and 0x19.

BUG=b:65437780

TEST=Add customized_leds register in devicetree.cb under target board,
	enable RT8168_SET_LED_MODE flag. Make sure the setting is
	programmed correctly to offset 0x18 and 0x19. Observed the
	LEDs were behaving as expected. Executed suspend/resume and
	the LEDs were still working as expected.
