[Stable-7.2.11 06/41] hw/rtc/sun4v-rtc: Relicense to GPLv2-or-later

[Michael Tokarev]

From: Peter Maydell <peter.maydell@linaro.org>

The sun4v RTC device model added under commit a0e893039cf2ce0 in 2016
was unfortunately added with a license of GPL-v3-or-later, which is
not compatible with other QEMU code which has a GPL-v2-only license.

Relicense the code in the .c and the .h file to GPL-v2-or-later,
to make it compatible with the rest of QEMU.
