d0a768b1c8 clk: stm32f7: retrieve PWR base address from DT
PWR IP is used to enable over-drive feature in
order to reach a higher frequency.
Get its base address from DT instead of hard-coded value

34255b92e6 tools: env: Add support for direct read/write UBI volumes
Up to now we were able to read/write environment data from/to UBI
volumes only indirectly by gluebi driver. This driver creates NAND MTD
on top of UBI volumes, which is quite a workaroung for this use case.

Add support for direct read/write UBI volumes in order to not use
obsolete gluebi driver.
