mb/asrock/h110m: fix VR domains configuration
1) VR domains current limit Icc max for Sky/Kaby Lake S is set based on the processor TDP [1]. Updates information about this 2) Sets VR voltage limit to 1.52V, as described in the datasheets [2,3] [1] Change-Id: I303c5dc8ed03e9a98a834a2acfb400022dfc2fde [2] page 112-119, 6th Generation Intel(R) Processor Families for S-Platforms, Volume 1 of 2, Datasheet, August 2018. Document Number: 332687-008EN [3] 7th Generation Intel(R) Processor Families for S Platforms and Intel(R) Core(TM) X-Series Processor Family Datasheet, Volume 1, December 2018, Document Number: 335195-003 Change-Id: I6e1aefde135ffce75a5d837348595aa20aff0513 Signed-off-by: Maxim Polyakov <max.senia.poliak@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/35067 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Georgi <pgeorgi@google.com>
