[PATCH master 1/2] hab: habv4: use explicitly unsigned types for pointers into SRAM

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

char is generally unsigned on ARM, but we shouldn't rely on that. HAB
code does though and compare a char against 0xdb, which would never
succeed if chars were signed. Switch to an explicitly unsigned type to
fix this.
