hw/arm/stellaris: Split stellaris-gptm into its own file
The implementation of the Stellaris general purpose timer module device stellaris-gptm is currently in the same source file as the board model. Split it out into its own source file in hw/timer. Apart from the new file comment headers and the Kconfig and meson.build changes, this is just code movement. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Damien Hedde <damien.hedde@greensocs.com> Message-id: 20210812093356.1946-24-peter.maydell@linaro.org
