This patch adds support for fake system suspend (SC7). This is a debug mode, to ensure that a different code path is executed for cases like pre-silicon development, where a full-fledged SC7 is not possible in early stages. This particular patch ensures that, if fake system suspend is enabled (denoted by tegra_fake_system_suspend variable having a non-zero value), instead of calling WFI, a request for a warm reset is made for starting the SC7 exit procedure. This ensures that the code path of kernel->ATF and back to kernel is executed without depending on other components involved in SC7 code path. Additionally, this patch also adds support for SMC call from kernel, enabling fake system suspend mode.
