I can't imagine why that would be the case. My /lib/firmware structure looks a
bit like this, for my video card:
/lib/firmware/

... And the kernel .config:
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware/"
CONFIG_EXTRA_FIRMWARE="amdgpu/polaris10_ce.bin amdgpu/polaris10_ce_2.bin
amdgpu/polaris10_k_smc.bin amdgpu/polaris10_k2_smc.bin
amdgpu/polaris10_k_mc.bin amdgpu/polaris10_mc.bin
amdgpu/polaris10_me.bin amdgpu/polaris10_me_2.bin
amdgpu/polaris10_mec2.bin amdgpu/polaris10_mec2_2.bin
amdgpu/polaris10_mec.bin amdgpu/polaris10_mec_2.bin

amdgpu/polaris10_rlc.bin amdgpu/polaris10_sdma1.bin

amdgpu/polaris10_smc_sk.bin amdgpu/polaris10_uvd.bin
amdgpu/polaris10_vce.bin"
It's tedious, but there's no reason that the kernel shouldn't find firmware in
subdirectories. Perhaps you needed to add a trailing oblique ('/') to your
CONFIG_EXTRA_FIRMWARE_DIR, such that the concatenated path is correct ?
