clocksource/drivers/timer-sp804: Fix read_current_timer() issue when clock source is not registered
Register a valid read_current_timer() function for the
SP804 timer on ARM32.
On ARM32 platforms, when the SP804 timer is selected as the clocksource,
the driver does not register a valid read_current_timer() function.
As a result, features that rely on this API—such as rdseed—consistently
return incorrect values.
To fix this, a delay_timer structure is registered during the SP804
driver's initialization. The read_current_timer() function is implemented
using the existing sp804_read() logic, and the timer frequency is reused
from the already-initialized clocksource.
