[U-Boot] [PATCH] lib: sha1: Change uint8_t to unsigned char for sha1_der_prefix array.

[Wilson Lee]

uint8_t used in sha1_der_prefix array was not able to recognize by
compiler when try to build the tools using 'HOSTCC'. That is because,
uint8_t is undefined when 'HOSTCC' is defined because asm/type.h is not
included in that case. Use unsigned char for sha1_der_prefix[] array
instead.

This commit is to remove and change the uint8_t to unsigned char for
sha1_der_perfix[] array.
