[U-Boot] [PATCH] hwconfig: Move HWCONFIG_BUFFER_SIZE into hwconfig.h

[York Sun]

Before proper environment is setup, we extract hwconfig and put it into a
buffer with size HWCONFIG_BUFFER_SIZE. We need to enlarge the buffer to
accommodate longer string. Since this macro is used in multiple files, we
move it into hwconfig.h.
