The pvlock_page and hvclock_page variables are (as the name implies)
addresses to pages, created by the linker script.
But we declared them as just "extern u8" variables, which _works_, but
now that gcc does some more bounds checking, it causes warnings like
warning: array subscript 1 is outside array bounds of ‘u8[1]’
when we then access more than one byte from those variables.
Fix this by simply making the declaration of the variables match
reality, which makes the compiler happy too.
