After adding the clock subsystem to the SOC, the dummy
clocks clk26m and clk32k are not longer needed. Delete them.

clk26m is referenced by drivers/clk/mediatek/clk-mt6797.c:
static const char * const axi_parents[] = {
"clk26m",
"syspll_d7",
"ulposc_axi_ck_mux",
};
Please just delete clk32k which is dummy, and keep clk26m. Or might get
PLL wrongly.
Thanks.
