[3/3] boot/at91bootstrap3: add BR2_TARGET_AT91BOOTSTRAP3_NEEDS_PYTHON3

From: Eugen Hristev <eugen.hristev@microchip.com>

Some at91bootstrap3 configurations now use Python scripts on the host
for NAND/PMEC related utilities. In order to be able to use those
scripts, this commit adds a new
BR2_TARGET_AT91BOOTSTRAP3_NEEDS_PYTHON3 which allows to express the
need for host-python3 as a dependency to build at91bootstrap3.

[Thomas: this was extracted from a patch from Eugen adding
at91bootstrap 4.x support.]

Hi,

This prompt that appears in menuconfig is a bit unfriendly : it does not 
say who needs the host-python3, and it does not appear to be in the 
at91bootstrap3 -related options.
It is at the same indentation level as the other bootloaders, like 
Barebox, Grub, etc. So I think it's misleading and should be aligned 
with the other At91bootstrap options

Crap, you're entirely right, it is misplaced: it should have been just
two line above, within the if BR2_TARGET_AT91BOOTSTRAP3 ... endif block.

Unless someone beats me at it, I'll send a patch fixing that.

Thanks for spotting this!
