feat(lib): add mmio read with timeout

In several cases, drivers poll a register using a blocking 'while'
or 'for' loop without a timeout mechanism. Introducing a timeout
would be beneficial, as it allows the system to log an error and
delegate the decision to the caller - whether to continue execution
or halt with a panic.

To address this, the mmio_read_poll_timeout() helper can be used. It
exits with -ETIMEDOUT if the timeout is reached, or 0 on success.
Additionally, the final value read from the register is stored in the
'val' variable, avoiding the need for an extra read after polling
completes.
