new port's shar
This port adds u-boot for Zybo Z7 board into ports collection. It is tested to build working binaries suitable for dropping into armv7-genericsd image's MSDOSBOOT partition to provide working system, just valid DTB file needs to be added to it (not part of this port, naturally).
Tested with currently used 2019.10 u-boot distfile, it works with recently released 2020.01 too (builds and boots).
Patches for two init issues are included in this port - there is bad clock in defconfig file for UART and two MIO pins are initialized incorrectly with pull-ups activated. Both are reported already upstream, but could not be included in release before 2020.04, naturally, so in the meantime use simple patches in this port.
