Subject: [PATCH] net: ti/cpsw_new: Expose the same module parameters as ti/cpsw.

The "old" CPSW driver (cpsw.c) exports the following module parameters:

	- ti_cpsw.debug_level
	- ti_cpsw.ale_ageout
	- ti_cpsw.rx_packet_max
	- ti_cpsw.descs_pool_size

This patch exposes the same parameters for the "new" CPSW driver:

	- ti_cpsw_new.debug_level
	- ti_cpsw_new.ale_ageout
	- ti_cpsw_new.rx_packet_max
	- ti_cpsw_new.descs_pool_size

It seems like consistency between the two drivers is a reasonable goal.
