[meta-freescale] Moving linux-fslc to 3.12-rc4

[Fabio Estevam]

Hi,

I would like to propose that we move linux-fslc from 3.11 to 3.12-rc4
as we have a better support for i.mx in 3.12:

- mx53 USB host support
- SATA on mx6
- SPDIF
- USB gadget support
- Fixes on mxs-lradc

Linus usually go up to -rc7, which means that the final 3.12 would
happen about 4 weeks from now.

The idea would be to move to 3.12-rc4 now and update it for every rc
release until 3.12 is out. This is similar to what we are currently
doing with U-boot.

Please let me know your thoughts.

Regards,

Fabio Estevam
