ASoC: fsl: lpc3xxx: Make some symbols static
These symbols are not used outside of the files, make them static to fix
sparse warnings:

sound/soc/fsl/lpc3xxx-i2s.c:261:30: warning: symbol 'lpc3xxx_i2s_dai_ops' was not declared. Should it be static?
sound/soc/fsl/lpc3xxx-i2s.c:271:27: warning: symbol 'lpc3xxx_i2s_dai_driver' was not declared. Should it be static?
sound/soc/fsl/lpc3xxx-pcm.c:55:39: warning: symbol 'lpc3xxx_soc_platform_driver' was not declared. Should it be static?

We already have snd_pcm_direction_name(). Let's use it.

ASoC: fsl: lpc3xxx-i2s: Remove set but not used variable 'savedbitclkrate'
The variable savedbitclkrate is assigned and never used, so can be removed.

sound/soc/fsl/lpc3xxx-i2s.c:42:13: warning: variable ‘savedbitclkrate’ set but not used [-Wunused-but-set-variable]

ASoC: fsl: lpc3xxx-i2s: Avoid using ret uninitialized in lpc32xx_i2s_probe()
clang points out that ret may be used uninitialized in
lpc32xx_i2s_probe() in an error pointer path (which becomes fatal with
CONFIG_WERROR):

  sound/soc/fsl/lpc3xxx-i2s.c:326:47: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized]
    326 |                                      "failed to init register map: %d\n", ret);
        |                                                                           ^~~
  sound/soc/fsl/lpc3xxx-i2s.c:310:9: note: initialize the variable 'ret' to silence this warning
    310 |         int ret;
        |                ^
        |                 = 0
  1 error generated.

One solution would be a small refactoring of the second parameter in
dev_err_probe(), PTR_ERR(i2s_info_p->regs), to be the value of ret in
the if statement. However, a nicer solution for debugging purposes,
which is the point of this statement, would be to use the '%pe'
specifier to symbolically print the error pointer value. Do so, which
eliminates the uninitialized use of ret, clearing up the warning.

ASoC: fsl: Add i2s and pcm drivers for LPC32xx CPUs
This driver was ported from an old version in linux 2.6.27 and adjusted
for the new ASoC framework and DMA API.
