zephyr: fix invalid select for USB-C PPC RT1718S
zephyr: fix invalid select for USB-C PPC RT1718S

The Kconfig option had invalid name after 'select' command
which resulted in no Kconfig being selected. Fixing this misspell
caused the compilation error due to the cyclic dependency.
This commit removes the 'select' command since it wasn't working anyway.
