Changes

#1 Change eMMC (U6) from IS21ES08G-JCLI / IS21ES64G-JCLI to SDINBDG4-8G-XI2 / SDINBDG4-64G-XI2

Type: BOM change
Reason: Distributor informed about unforseeable immediate EOL of parts. No official documents form manufacturer are avaialble. No LTB, already confirmed orders were canceled by distributor/manufacturer. 
Impact: None. Replacement has same capacity as used on corresponding affected variant. Reference designs for vivado versions 2019.2 and 2020.2 were tested and work properly without any changes.

#2 Clock Revision Change (U14) SiT8008AI-73-XXS-52.000000E to SiT8008BI-73-XXS-52.000000E

Type: BOM change
Reason: Switch to actual revision. Revision A devices may be discontinued.
Impact: None. 

#3 Change Ferrite Beads (L1, L2, L3, L4, L5, L7, L9, L10, L11, L12) BKP0603HS121-T to MPZ0603S121HT000

Type: BOM change
Reason: Part is NRND and EOL announced.
Impact: None. DC resistance decreased from 150mOhm to 130mOhm, rated current increased from 0.85A to 1A.
