mtd: physmap_of: Loop through all "reg" tuples for mapping

This patch changes the loop over the "reg" tuples to not exit
directly upon of_address_to_resource() failure but to continue
with the next "reg" tuple instead. This failure could be due to
size = 0, which might be passed via the device-tree.

This is needed for boards, where a "reg" tuple might have size 0
(of_address_to_resource() returns with EINVAL when size = 0).

Example:

Fully equipped board:

	reg = <0 0x00000000 0x00400000
	       0 0x00400000 0x00400000>;

Partially equipped board:

	reg = <0 0x00000000 0x00400000
	       0 0x00400000 0x00000000>;

This could be the case on boards with runtime detection of
multiple NOR flash configurations where the detected flash size
is inserted into the dtb in U-Boot.
