msi-laptop: merge quirk tables to one 

This patch introduced a quirk_entry struct, then we merged all quirk
tables to msi_dmi_table. Then we can more easily to set different quirk
attributes for different machine.

Signed-off-by: Lee, Chun-Yi <jlee@suse.com>

Changed this patch so that it could be applied before MSI Wind U100
support patch. Changed rfkill logic for ec_read_only quirk support.
Removed delays if ec_delay = false.
