monitor_pages was a void pointer, containing an unknown number of arrays that
we just "knew" were a child and parent array of a specific size.  Instead of
that implicit knowledge, let's make them a real pointer, allowing us to have
type safety, and a semblance of sane addressing schemes.

This patch is the first in a series that moves the hv bus code to use the
dev_groups field instead of dev_attrs, as dev_attrs is going away in future
kernel releases.

It moves the id sysfs file to the dev_groups structure, and creates the needed
show/store functions, instead of relying on one "universal" function for this.
By doing this, it removes the need for this to be in a temporary structure.

fixmem32 is assigned to address of res->data member
so the address is always valid

Actually since we are not checking for res != NULL
static analyzing is complaining about referencing the pointer
and consequent check for null.

bmp085_get_of_properties() is called by bmp085_init_client() which is
called by bmp085_probe() which is an EXPORT_SYMBOL_GPL function.

bmp085_probe() is really used as a probe function by another modules
(e.g. bmp085-i2c.c, bmp085-spi.c).

Except bmp085_get_of_properties(), all functions have no '__init', so
need remove '__init' from bmp085_get_of_properties() too, or at least,
it will report related warning:

  WARNING: vmlinux.o(.text+0x4c8a07): Section mismatch in reference from the variable .LM171 to the variable .init.text:_bmp085_get_of_properties
  The function .LM171() references
  the variable __init _bmp085_get_of_properties.
  This is often because .LM171 lacks a __init
  annotation or the annotation of _bmp085_get_of_properties is wrong.
