Subject: mx6qsabre_common: Let mmc partition be board specific

commit 49ea0ff5 (49ea0ff5) introduced CONFIG_SYS_MMC_ENV_PART into mx6qsabresd.h
to store the mmc partition, but in order for it to have effect we should place
it into 'mmcpart' variable.

Also add CONFIG_SYS_MMC_ENV_PART into mx6qsabreauto.h.

Subject: net: fec_mxc: delete CONFIG_FEC_MXC_MULTI

It is more logical to test for CONFIG_FEC_MXC_PHYADDR
to determine whether to define the function fecmxc_initialize.

Subject: phy: add phy_find_by_mask/phy_connect_dev

It is useful to be able to try a range of
possible phy addresses to connect.

Also, an ethernet device is not required
to use phy_find_by_mask leading to better
separation of mii vs ethernet, as suggested
by Andy Fleming.
