Subject: [PATCH net-next 01/12] net: stmmac: replace has_integrated_pcs field with a flag

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

struct plat_stmmacenet_data contains several boolean fields that could be
easily replaced with a common integer 'flags' bitfield and bit defines.

Start the process with the has_integrated_pcs field.
