staging: omap-thermal: create header for register, bitfields and defi…
…nitions In order to have a better code readability and organization, this patch splits omap-bandgap.h into three headers. . omap-bandgap.h will contain only the driver related data structures definitions and macros . omap4xxx-bandgap.h will contain only defines and bitfields related to OMAP4 based devices . omap5xxx-bandgap.h will contain only defines and bitfields related to OMAP5 based devices Signed-off-by: Eduardo Valentin <eduardo.valentin@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
