Subject: [PATCH] clocksource/drivers/timer-ti-dm: add module build support

Add missing MODULE_LICENSE variable and convert bool to tristate in
Kconfig to be able to build driver in module.

By default this driver was set at y when ARCH_K3=y.

Enable possibility to build in module timer-ti-dm driver needed in
Android context and Android Generic Kernel Image support.

I know any other clicksource driver support module build but i do test on AM62X and
AM62P EVM board and i able to use this driver and test it with PWM.

By default this driver will be always enable in bultin when ARCH_K3=y so
no impact for other TI SoC.
