drivers: gpio_mcux_lpc: Fix xt-clang error

Remove gpio_clock_names and gpio_mcux_lpc_config->clock_ip_name from
drivers/gpio/gpio_mcux_lpc.c.

The drivers/gpio/gpio_mcux_lpc.c file did not compile with xt-clang
RI-2021.8-win32, as the gpio_clock_names was initialised with a
reference to a static const array. The clock_ip_name member was
initialised from this variable, but it isn't used anywhere else.
