watchdog: rzg2l_wdt: Fix 32bit overflow issue

In the Linux kernel, the following vulnerability has been resolved:

watchdog: rzg2l_wdt: Fix 32bit overflow issue

The value of timer_cycle_us can be 0 due to 32bit overflow.
For eg:- If we assign the counter value "0xfff" for computing
maxval.

This patch fixes this issue by appending ULL to 1024, so that
it is promoted to 64bit.

This patch also fixes the warning message, 'watchdog: Invalid min and
max timeout values, resetting to 0!'.

CWE-190 Integer Overflow or Wraparound

The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
