projects/cn0577: Remove ADAQ2387x from CN0577

[StancaPop]

PR Description

1. docs/projects/cn0577:

• Removed the ADAQ2387X supported boards from the CN0577 documentation, because now they will have a separate documentation page
• Removed ADC_RES mentions, since CN0577 supports only the LTC2387-18 part.
• Updated block diagram

2. projects/cn0577:

• Remove ADC_RES & OUT_RES parameters, since the resolution is fixed to 18b
• Update READMEs
