platform: tegra: la: Use clk_get_sys()

Instead of using clk_get(), use clk_get_sys() so we avoid the "wildcard"
EMC clock matching.

This patch is part of a series of patches to fix a camera underflow due
to missing emc clocks in IsoMgr. To correctly fix that bug we need to
remove the EMC wildcard match. As a result all usages of the EMC wildcard
matching need to be removed.
