[PATCH] dell-laptop: Use buffer with 32-bit physical address

[<Stuart_Hayes@xxxxxxxx>]

Calls to communicate with system firmware via a SMI (using dcdbas) need
to use a buffer that has a physical address of 4GB or less.  Currently
the dell-laptop driver does not guarantee this, and when the buffer
address is higher than 4GB, the address is truncated to 32 bits and the
SMI handler writes to the wrong memory address.
