[U-Boot] [PATCH] test/py: gpt: update size of gpt partition

[Patrick Delaunay]

- avoid disturbing 0MiB partition size (in fact < 1MiB)
- test overlap limit between part1 and part2
- test gpt write with data with modifier 'M' for MiB

Modification was initially proposed by Stephen Warren in review of
[PATCH v1 1/3] test/py: gpt: update test_gpt

From: Stephen Warren [mailto:swarren at wwwdotorg.org]
  If you're looking for more things to change(!), perhaps
  change the sgdisk commands so that the partitions are
  big enough that 'gpt read host 0' says something other
  than 'size 0MiB' for the partitions; when I saw that,
  I was initially rather confused until I realized that
  the partitions were less than 1MiB!

  I don't really looking...
  but I agree: size 0MiB is confusing,
  I had the same reaction the first time.

  So I will propose something when this serie will be accepted,
  just update the test to have 2 partitions with different size
  and > 1MiB.
