Subject: [PATCH] xspiloader: Avoid spurious TIM12 interrupts

When the timer is enabled, interrupts will continue after the payload
boots, causing spurious interrupts (unless TIM12 is reconfigured by the
booted program). That would result in hitting DefaultHandler after the
program runs.

xspiloader doesn't need embassy-time, so don't enable any time driver.
TIM12 is the default timer driver interrupt.

This doesn't affect usbnvme since that uses embassy-time and configures
TIM12. It could affect other programs loaded by xspiloader, using newer
embassy-stm32 or other configurations.
