Subject: [PATCH 6/9] net: cwdavinci_cpdma: export symbols for cpsw

With the support for ARM AM33xx in multiplatform kernels
in 3.9, an older bug appears in ARM allmodconfig:
When the cpsw driver is built as a module with cpdma
support enabled, it uses symbols that the cpdma driver
does not export.

Without this patch, building allmodconfig results in:

ERROR: "cpdma_ctlr_int_ctrl" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!
ERROR: "cpdma_control_set" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!
ERROR: "cpdma_ctlr_eoi" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!
