projects/cn0577 & library/axi_ltc2387: Add make parameters
- projects/cn0577: Added make parameters ADC_RES (the ADC input resolution) and TWOLANES (two-lane mode or one-lane mode). Also fixed the sysid parameters logging - library/axi_ltc2387/axi_ltc2387_if.v: Changed the parameter name RESOLUTION to ADC_RES, as it was redundant Signed-off-by: Iulia Moldovan <Iulia.Moldovan@analog.com>
