Subject: [PATCH 08/11] memory: atmel-ebi: move NUM_CS definition inside
 atmel-ebi

From: Tudor Ambarus <tudor.ambarus@...rochip.com>

The total number of cs lines is described by the EBI controller
and not by the matrix. Move the definition for the number of cs
inside ebi driver. Drop "matrix" from its name.
