Subject: [PATCH v8 0/7] Qualcomm's lpass-hdmi ASoC driver to support audio over dp port

These patches are to support audio over DP port on Qualcomm's SC7180 LPASS
Asoc. It includes machine driver, cpu driver, platform driver updates for 
HDMI path support, device tree documention, lpass variant structure 
optimization and configuration changes.
These patches depends on the DP patch series
https://patchwork.kernel.org/project/dri-devel/list/?series=332029
https://lore.kernel.org/patchwork/project/lkml/list/?series=464856

changes since V7:
    -- Fixed typo errors
    -- Separated buffer size change patche
changes since V6:
    -- Removed compile time define flag, which used for enabling
     HDMI code, based on corresponding config param is included.
    -- Updated reg map alloc API with reg map bulk API.
    -- Removed unnecessary line splits
changes since V5:
    -- Removed unused struct regmap *map in lpass_platform_alloc_hdmidmactl_fields.
    -- DMA alloc and free API signature change in lpass-apq8016.c, lpass-ipq806x.c 
    -- Keeping API "irqreturn_t lpass_platform_hdmiif_irq" under ifdef macro
Changes Since v4:
    -- Updated with single compatible node for both I2S and HDMI.
Changes Since v3:
    -- Removed id in lpass variant structure and used snd_soc_dai_driver id.
Changes Since v2:
    -- Audio buffer size(i.e. LPASS_PLATFORM_BUFFER_SIZE) in lpass-platform.c increased.
Changes Since v1:
    -- Commit messages are updated
    -- Addressed Rob Herring review comments
