[PATCH v2 RESEND 06/14] soundwire: optimize sdw_dp0_prop

[Bard Liao <yung-chuan.liao@xxxxxxxxxxxxxxx>]

From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>

Move pointers and booleans.

Before:

struct sdw_dp0_prop {
	u32                        max_word;             /*     0     4 */
	u32                        min_word;             /*     4     4 */
	u32                        num_words;            /*     8     4 */

	/* XXX 4 bytes hole, try to pack */

	u32 *                      words;                /*    16     8 */
	bool                       BRA_flow_controlled;  /*    24     1 */
	bool                       simple_ch_prep_sm;    /*    25     1 */

	/* XXX 2 bytes hole, try to pack */

	u32                        ch_prep_timeout;      /*    28     4 */
	bool                       imp_def_interrupts;   /*    32     1 */

	/* size: 40, cachelines: 1, members: 8 */
	/* sum members: 27, holes: 2, sum holes: 6 */
	/* padding: 7 */
	/* last cacheline: 40 bytes */
};

after:

struct sdw_dp0_prop {
	u32 *                      words;                /*     0     8 */
	u32                        max_word;             /*     8     4 */
	u32                        min_word;             /*    12     4 */
	u32                        num_words;            /*    16     4 */
	u32                        ch_prep_timeout;      /*    20     4 */
	bool                       BRA_flow_controlled;  /*    24     1 */
	bool                       simple_ch_prep_sm;    /*    25     1 */
	bool                       imp_def_interrupts;   /*    26     1 */

	/* size: 32, cachelines: 1, members: 8 */
	/* padding: 5 */
	/* last cacheline: 32 bytes */
};
