[U-Boot] [PATCH v3 05/26] SPL: tiny-printf: ignore "-" modifier

[Andre Przywara <andre.przywara@arm.com>]

tiny-printf does not know about the "-" modifier, which aligns numbers.
This is used by some SPL code, but as it's purely cosmetical, we just
ignore this modifier here to avoid changing correct printf strings.
