u-boot-fslc: Avoid restricting parsing for 'imx'
The u-boot-fslc does not amend other machines and then cannot be seen
as something that poison other BSP. Adding the restriction to the
common file makes all native tools incompatible.
Fixes:
,----
| [imx23evk] ERROR: Nothing PROVIDES 'u-boot-mxsboot-native'
| [imx23evk] u-boot-fslc-mxsboot-native PROVIDES u-boot-mxsboot-native
| but was skipped: incompatible with machine imx23evk (not in
| COMPATIBLE_MACHINE)
