Subject: [RFC PATCH v1 06/12] omap: Replace strstarts() by str_has_prefix().

From: Francis Laniel <laniel_francis@...vacyrequired.com>

The two functions indicates if a string begins with a given prefix.
The only difference is that strstarts() returns a bool while str_has_prefix()
returns the length of the prefix if the string begins with it or 0 otherwise.
