[ Upstream commit a65083fa663a335008e34f65e184041174a9dc7e ]
CLK_INFRA_SSPM_32K_SELF has the "f_f26m_ck" clock assigned as its parent. This is inconsistent as the clock is part of a group that are all gates without dividers, and this makes the kernel think it runs at 26 MHz.
After clarification from MediaTek engineers, the correct parent is actually the system 32 KHz clock.
