[PATCH] power: reset: ltc2952: fix float conversion error

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

clang-14 does not like the way this driver converts a 'long double'
to an integer when the target architecture disables floating point
support:

drivers/power/reset/ltc2952-poweroff.c:162:28: error: expression requires  'long double' type support, but target 'x86_64-unknown-linux' does not support it
        data->wde_interval = 300L * 1E6L;
                                  ^

Turn this into pure integer math and make it more readable at the
same time using the NSEC_PER_MSEC macro instead.

Fixes: 6647156c00cc ("power: reset: add LTC2952 poweroff driver")
