PATCH v2 1/1 clocksource: tcb_clksrc: Fix clock speed message

The clock speed displayed at boot in an information message was 500 kHz too high compared to its real value. As the value is not used anywhere, there is no functional impact.

Fix the rounding formula to display the correct value.

---
v2: rebase over v4.15-rc1

There is no specified maintainer for this file, only supporters. Nicolas, could you pick this through the at91 tree as the TCB block is an AT91 peripheral ?

That is not correct, it defaults to Thomas and me, the maintainers of drivers/clocksource :)

Nicolas, do you agree with this change ? If yes, I will take it.
