Nikita Kiryushin f39c3d578c ACPI: LPIT: Avoid u32 multiplication overflow 
[ Upstream commit 56d2eeda87995245300836ee4dbd13b002311782 ]

In lpit_update_residency() there is a possibility of overflow
in multiplication, if tsc_khz is large enough (> UINT_MAX/1000).

Change multiplication to mul_u32_u32().

Found by Linux Verification Center (linuxtesting.org) with SVACE.
