According to the vendor [1] these HATs share the same DT overlay:
hifiberry-dacplus. The PCM512x-compatible control unit is attached to
I2C, so the additional snd-soc-pcm512x-i2c kernel module is required.
Also explicitly note the Amp2 support to reduce confusion for those
users.

(added bcm27xx tag, changed commit message)

When building an image for the bcm27xx target, some combinations of
config options will fail to build due the SND_SOC_AD193X_I2C and
SND_SOC_AD193X_SPI kernel config symbols being missing.
The problem only occurs on bcm27xx as the target contains a patch that
modifies the Kconfig file containing the symbols; in the vanilla kernel,
there is no string after the tristate keyword so the symbol is not
exposed.
The _I2C symbol depends on I2C, which is enabled in the kernel configs
of all bcm27xx subtargets.
The _SPI symbol depends on SPI_MASTER, which is exposed by either
kmod-mmc-spi, kmod-spi-bitbang, kmod-spi-dev, kmod-spi-bcm2835 or
kmod-spi-bcm2835-aux.
Both symbols are defined in the sound/soc/codecs directory, which is
only included when SND_SOC is enabled, so this problem doesn't occur
when kmod-sound-soc-core is not enabled. As the
kmod-sound-soc-bcm2835-i2s package disables the SND_SOC_AD193X_SPI
symbol, it also doesn't occur when kmod-sound-soc-bcm2835-i2s is
enabled.
As there are several possible config combinations that do exhibit this
problem, it is best to solve it by adding the missing symbols to the
subtarget kernel configs. By doing this we can remove them from the
kmod-sound-soc-bcm2835-i2s package.

This change makes the names of Broadcom targets consistent by using
the common notation based on SoC/CPU ID (which is used internally
anyway), bcmXXXX instead of brcmXXXX.
This is even used for target TITLE in make menuconfig already,
only the short target name used brcm so far.
Despite, since subtargets range from bcm2708 to bcm2711, it seems
appropriate to use bcm27xx instead of bcm2708 (again, as already done
for BOARDNAME).
This also renames the packages brcm2708-userland and brcm2708-gpu-fw.
