media: chips-media: wave5: drop "sram-size" DT property

Move the excessive "sram-size" device-tree property to the device match
data. Also change the SRAM memory allocation strategy, instead of
allocating exactly sram_size bytes, allocate all available SRAM memory
up to sram_size. Add the placeholders wave5_vpu_dec_validate_sec_axi()
and wave5_vpu_enc_validate_sec_axi() to validate that the allocated SRAM
memory is sufficient to decode/encode bitstream with a given resolution.
