linux-fslc-imx: upgrade to rel_imx_5.4.24_2.1.0 from NXP
NXP released a new BSP, which included a new kernel branch
imx_5.4.24_2.1.0. This branch was picked up into linux-fslc repository
and received an update up to v5.4.67 tag from stable korg.
New release from NXP requires the new kernel branch to be used, so
switch the kernel recipe to a new branch as well.
Update defconfig file to align with imx_v8_defconfig provided by NXP and
used as a base kernel configuration file for i.MX8 family, and
imx_v7_defconfig which is used for i.MX6/7 families.
Tracking information has been updated to reflect the state of the new
branch; all NXP-specific patches are tracked to be present in the base
NXP delivery and therefore were removed from the tracking list; all
critical patches are also verified to be present in the updated kernel
branch; specific cherry-picks are moved to new branch as well.
