Current U-Boot is an old version and fails to build:
/usr/bin/ld: scripts/dtc/dtc-parser.tab.o:(.bss+0x10): multiple definition of `yylloc'; scripts/dtc/dtc-lexer.lex.o:(.bss+0x0): first defined here
Bump U-Boot to fix the problem.
Latest U-Boot has switched to distro boot and SPL, so make the necessary
changes to support it. Other advantage of bumping U-Boot is that
it also supports the other imx6ul-pico variants.
While at it, also bump U-Boot to the 5.15 LTS.
