The size of the struct tegra_powergate is quite big and if any more
fields are added to the internal genpd structure, following warnings are
thrown:
drivers/soc/tegra/pmc.c:577:1: warning: the frame size of 1176 bytes is larger than 1024 bytes [-Wframe-larger-than=]
Avoid such warnings by allocating the structure dynamically.
