hw: Use properly sized asm type in boot_modules.s

Browse Source 
The boot modules assembled by the generated boot_modules.s file is
accessed from core using struct Bm_header. Unfortunately the assembler
.long directive is synonym to .int [1] and thus has the same size as the
C++ int type and *not* long. Use the matching assembly type .quad in
boot_modules.s when generating the file for 64-bit platforms such as
x86_64.
