Subject: [PATCH 1/2] net: ethernet: ti: select PAGE_POOL for switchdev driver

The new driver misses a dependency:

drivers/net/ethernet/ti/cpsw_new.o: In function `cpsw_rx_handler':
cpsw_new.c:(.text+0x259c): undefined reference to `__page_pool_put_page'
cpsw_new.c:(.text+0x25d0): undefined reference to `page_pool_alloc_pages'
drivers/net/ethernet/ti/cpsw_priv.o: In function `cpsw_fill_rx_channels':
cpsw_priv.c:(.text+0x22d8): undefined reference to `page_pool_alloc_pages'
cpsw_priv.c:(.text+0x2420): undefined reference to `__page_pool_put_page'
drivers/net/ethernet/ti/cpsw_priv.o: In function `cpsw_create_xdp_rxqs':
cpsw_priv.c:(.text+0x2624): undefined reference to `page_pool_create'
drivers/net/ethernet/ti/cpsw_priv.o: In function `cpsw_run_xdp':
cpsw_priv.c:(.text+0x2dc8): undefined reference to `__page_pool_put_page'

Other drivers use 'select' for PAGE_POOL, so do the same here.
