[PATCH] staging: tidspbridge: fix build error for missing variable

Commit:
staging: tidspbridge: gen: simplify and clean up
There is recently added hex_to_bin() kernel's method which we could use
instead of custom long function.

Introduced usage of hex_to_bin without defining the temp variable.
this causes the build error:
drivers/staging/tidspbridge/gen/uuidutil.c: In function 'uuid_hex_to_bin':
drivers/staging/tidspbridge/gen/uuidutil.c:63: error: 'value' undeclared (first use in this function)
drivers/staging/tidspbridge/gen/uuidutil.c:63: error: (Each undeclared identifier is reported only once
drivers/staging/tidspbridge/gen/uuidutil.c:63: error: for each function it appears in.)

introduce variable value to fix the error.
