Also remove "-fpie" because this won't work with it enabled, most likely
because "-fpie" creates some .got* sections that probably should be
loaded into "RAM" (0x00231000) at some point, but that never happens
since those sections aren't in the linker script. As it is now, even
with the option enabled, the code was never truly position-independent
due to the fixed "RAM" address, so once I fix that issue (by letting RAM
start immediately after ROM), have a separate .rodata section without
the executable bit set (for cleaner disassembly), and properly load the
.got* sections, I can re-enable that option.

Eventually this will be used to init PMIC/DRAM.

I'm not sure what the ME ID is, but it seems to be device-specific, and
it's only available in BROM DL mode.

Add "disable" functionality, enable specifying timeout, enable
configuration without resetting.

This is probably the "more correct" way of starting a bare-metal C
program. Returning from main() will now enter a WFI loop.

For simplicity, the length of the DA entry should be kept in one place.
