fsl-default-providers.inc: Make virtual/kernel assigment delayed
In 01851da (machine/*: Allow kernel provider override) the assigment of preferred provider for virtual/kernel has been changed to a weak assignment. This works for most of cases but has caused a regression in some machines. When a machine includes the imx-base.inc file, the assignment is done and the intended setting of the machine does not take effect. For example, in the below code fragment: ,----[ Wandboard board configuration fragment ] | include conf/machine/include/imx-base.inc | ... | PREFERRED_PROVIDER_virtual/kernel ?= "linux-wandboard" `---- the virtual/kernel provider would be 'linux-imx' as, at the time of imx-base.inc inclusion, it was undefined. The expected behaviour would be to use 'linux-imx' /only/ when no setting has been done. The ??= operator solves this as it is used /only/ if no assignment is done to the virtual/kernel provider in the end of the parsing. So it gives the expected behaviour.
