arm64: topology: fix possible overflow in amu_fie_setup()
cpufreq_get_hw_max_freq() returns max frequency in kHz as *unsigned int*,
while freq_inv_set_max_ratio() gets passed this frequency in Hz as 'u64'.
Multiplying max frequency by 1000 can potentially result in overflow --
multiplying by 1000ULL instead should avoid that...
Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.
Fixes: cd0ed03a8903 ("arm64: use activity monitors for frequency invariance")
