[PATCH master 12/13] hw_random: fix compilation with 64-bit size_t

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

max has the type size_t, while data_size is a u32.
This doesn't matter for 32-bit OMAP, but has min() trigger a compile
error when compile testing for 64-bit. Add a cast via min_t to fix this.
