cmake: increase function inlining limit 

gcc sets the inlining limit a bit arbitrary and the default gcc
on the RPi2 seems to use a lower value so compiling the SIMD
extensions fails with an "inlining failed" error in
srslte_mat_2x2_mmse_csi_simd().

this patch increases the default value. even though its
increased for all platforms it shouldn't case issues on other
machines. the value isn't used by clang.
